If I can point out, the Panama papers are no longer anonymous, since everyone knows about them... Also, the whole "what the powerful have" narrative is getting very old. While I am by no means rich, why do bitcoin fanatics always put the rich in the same caricature/box? You don't have to be rich to have access to this "anonymity", which is not really anonymous, since a company or group of people are holding all your information and you've off-loaded the risk onto them and you better pray they know how to truly hide things.
I would argue that bitcoin gives everyone access to a better mechanism, if they know how to use it. Money can surely make a big difference, but it's knowledge that truly makes the difference at the end of the day. Money will buy you someone else's knowledge, but it will never beat you having the knowledge yourself.
There's nothing stopping you from becoming rich, if you are willing to put in the effort and time, most people aren't and therefore will never be rich. It's trite to always blame the rich for everything. You may live in a country where they are more controlling and oppressive, but there's nothing stopping you from re-locating to a place that respects competition and will allow you to rise if you put in the effort. Is it easy? No, but it's better than complaining about the rich.
We will never know if we have the full list of people involved in Panama papers, as they weren't leaked in their raw form as a trusted source as Wikileaks would leak them. There is suspicious lack of US persona in it. Julian Assange spoke about this multiple times and said that he doesn't support the censorship they imposed. So it was more likely used to target certain people then actual leaking of sensitive information.
I also don't agree that rich must be a problem, I purposefully didn't mention the rich in my reply. However, money does give you power and the power of anonymity is one of them, so they aren't the problem, but the power they get compared to the rest is. There are people with power that aren't rich as well, but this doesn't excuse the rich, sense money always gives you power and they will always be part of this elite.
I don't discriminate against the rich, there is a lot of good folks that are rich and even use that wealth for good causes. However, I think that you are discriminating against the poor here, not out of a bad intent, but you simply can't understand the limits of poverty as you never saw it. For you it seems trivial to travel, but for the majority of people that are poor is not. You can't just buy a plane ticket if you are poor, you simply don't understand how poor majority of world population is, let along the millions of the poorest countries. Besides, getting into a developed country, like US for example, is not that easy either, even if you manage to get to there. During war time people have no choice, but to leave the country, it is either that or certain death, so they do their best to move. Many people died in the effort of migrating during a refugee crisis, as you might have seen pictures of toddles washing up on shore, that to be honest, the world wouldn't even hear about if it wasn't a shore of a developed country. And the ones who got to their destination safely went to an incredible amount of effort and huge risk for their lives and future. It is not as easy as you might think. No one is insane enough to not get out of a country they have no future in, but it isn't easy. You know the amount of problems European countries had with these people migrating peacefully. It isn't that easy to move and it is even harder to get accepted once you do.
Ok I won't argue any more that Bitcoin is not anonymous but rather pseudo-anonymous, there are thousands google links out there to show you exactly that.
If you don't take this fact but try to convince yourselves and possibly others that bitcoin is anonymous, I guarantee that you are on the wrong path. Today you might create a random bitcoin address, buy some BTC from a bitcoin ATM or from someone on the street and there you are, having some bitcoins on your random anonymous address. In that sense, yes you are anonymous. You might even manage to move these funds around by those tricks some of you described, like using an exchange in the middle (by providing bogus identification, I seriously would not go to that direction since you are falsifying documents, which is a crime - and don't tell me it is not because you are not hurting anyone blah blah blah).
But I did not start this thread talking about how we use cryptocurrencies today. (where 99.99% of us treat it as an investment).
I am talking about a a day in the future where bitcoin (or some other cryptocurrency) might become mainstream.
This means getting your salary paid in BTC, pay your rent in BTC, take a loan in BTC, buy your holiday vacation in BTC, pay your children's school in BTC, pay the restaurant in BTC, pay your doctor in BTC.
(Replace BTC with ETH or another crypto of your choice which does not offer anonymity, so no ZEC or XMR)
In such a situation, NO, you are NOT anonymous whatsoever. Period.
There are two things you might be missing here. First, there are many things like Bitcoin mixers and decentralized exchanges, even marketplaces and so on. Even sending to a newly generated address before paying for stuff will give you a deniable accountability, by allowing you to claim that that address isn't yours and that you sent the funds to it. So staying anonymous with Bitcoin isn't impossible at all, but you need to have rest of the services work with you on this most of the time, these services could be anonymous by themselves, they need Bitcoin. That is the second point, Bitcoin is anonymous, you need no personal information to use it, it is using these other services that expose you, but that can be fixed as well and certain parts of it already are.
As for the bogus identification, you already know my stance from my previous posts.
The answer to your question is, all of the privacy we can get, as I still never heard of a good argument on why not or even on how would be possible to stop these private technologies in a first place. It is important to keep in mind that wondering on how world should look like makes no sense if there is only one possible way it can go and will go. What is the point of the question when there will be better and better privacy no matter what you do. You can't stop it, it isn't your choice to make, you don't have an alternative option.
