I am not religious. I quote Satoshi for facts, not beliefs. Smarter people have taken over development, and have found much more viable ways to scale bitcoin.
People also quote Satoshi in the interests of maintaining a coherent vision of a monetary model, not just for 'religious' reasons or for referencing 'facts'.
I've read a lot of your posts and you make a very solid case for supporting the bitcoin "consensus", however you've got to acknowledge that those priorities may come with a potentially damaging price tag of ending up with a very different monetary reality than what was originally envisaged by the "Satoshi" ideal.
What is Satoshi's ideal? He wanted to create anonymous cash for the internet. It turned out to be not anonymous at all. Should we fix that?
He didn't see any good ways to scale, except for increasing blocksize and centralize the blockchain. Now that we know better, should we do it?
He didn't want people to mine with their GPUs, becuase he had ment that every user should mine ("vote") with their CPUs. Then we got FPGA mining, and now we even have large centralized ASIC mining factories. Should we fix that?
For a start, what you call "more viable ways to scale bitcoin" are not really scaling bitcoin at all. They are putting in place scaffolding out in the eco-system so that bitcoin doesn't have to scale. It's basically just 1990's Microsoft Transaction Server funnelling traffic into more digestable chunks. But what are the implications of this for the original vision of a single-tier monetary model ?
More viable ways scales up the parts of bitcoin which needs to scale up. We need to make it possible to transact faster, cheaper and more often. We do not need to increase the amount of resources needed for every node in the system.
Thats the real question that needs investigated IMO. The more bitcoin loses any integral ability to scale or transact instantly, the more it can kiss goodbye any pretence of a role as electronic "cash" in a true monetary sense. The settlement-layer concept is a very different type of animal and is not a financial model that should be stumbled into unconsciously. You can't just say at the start "hey, we're electronic cash" and then later "hey we changed our minds, we're settlement layer for credit transactions cos we had a few technical problems".
The Bitcoin blockchain was designed as a settlement layer. It has never been possible to transact instantly with Bitcoin. 0 confirmation transactions have the same security as "the check is in the mail". If I had sent bitcoin to an excange an hour ago now, the transaction would only have four confirmations. I would need two more confirmations before my coins are credited, and I can exchange them for money. Lightning can enable instant transactions by building on top of the settlement layer below, where the transaction, or the start and endpoint of a chain of transactions, will be commited later.
The fact is that commercial pressure is remoulding Bitcoin from the original vision of a universally accessible, ubiquitous electronic token, into no more than just another asset class. Although expressed in good faith, IMO your equally religious obsession with definitions of "consensus" is helping to push it down that road.
The commersial pressure from Coinbase and others, which are under strong regulatory pressure to do chain analysis and watch how their users are spending their money, have failed to gain much support. Instead they fake support by paying for lits of nodes at data centers, like
this. By enabling new technologies, Bitcoin can finally be this ubiquitous electronic token which is usable for everything from large settlements to instant micropayments.
Nor are concepts like sidechains going to help anything in this regard. All they do is address specialisation at the expense of fungibility (because you're having to recast the currency in a different identity to address a technical deficiency and therefore make one unit distinguishable from another). So all these monetary rules and principles are being broken just in order to address a load of technical deficiencies and preserve the "consensus" fork.
I think the opposite is true. Traditionally Bitcoin has only been usable for relatively fast (~ 1 hour) and cheap settlements worldwide 24/7. Not really for e.g. paying your bar tab at the end of a long evening. Not all bartenders will accept "the check is in the mail" as payment when you are about to leave. Both sidechains, payment channels and Lightning will make Bitcoin more flexible, useful for more purposes, and accessible to more people.
Those priorities seem to me to be the wrong way around. I think that bitcon's technical properties are optimal when they are in harmony with its monetary ones - not in conflict with them. However, the implications of that view are not too palatable to many of the core devs because it means that the "missing space" has to be taken up by altcoins and a true monetary market allowed to develop. They're not too hot on that idea.
I don't think an altcoin for every single purpose is a good idea. I remember travelling through Europe before the Euro. I was used to it then, but now I hope we never return to the pre-Euro days. It was a hassle to keep exchanging my money from one currency to another at every border, and of course the exchangers took a high percentage every time. Even if I didn't spend anything, I would get home with much less money than I had when I left. Imagine if each of the states in the US had a different currency. It would certainly limit free movement of capital inside the country.
