No no and no.
Who are you once again to dictate what crypto currencies should be used for and by whom ?
Sure, you can play with the toy. So what ? Apart from having the potential to give liberty back to its users, it only brings hassle. Everything in crypto is more difficult to do than in fiat. It is the price of liberty. I'm willing to pay that price, on the condition that I get what I pay for: liberty. If the idea is that liberty is taken away from crypto as much as it is from other means of payment (fiat), then there's no reason to use it, at all.
Cars bring liberty over trains. Trains, you have to take them at a specific moment, at a specific place (the railway station). But trains are easy to use: you pay your ticket, you go to the railway station, and you sit down in the train. Cars are much more of a pain: you have to take care of them yourself, buy petrol, repair them, and they are often more expensive to use. You have to drive them yourself. You can get lost, you can have an accident. But cars bring liberty: you can go where you want, when you want. That's why you pay that price.
Suppose now that one obliges car owners to park their car at the railway station, and only drive at specific times, following given tracks, to given destinations. In order to use your own car, you have to order a voyage with it in a given catalogue, you have to go at the specified time at the railway station, and drive it exactly as they tell you, to another railway station as they specify it to you. Owning a car would be totally ridiculous. You better take the train: less hassle. You've lost the extra liberty the car brought to you, it has to suit exactly the same rules and limitations as the train, and it only brings in extra costs and hassle.
Same with crypto. If crypto has to comply to everything fiat complies automatically to, then crypto is just more hassle. There's no need for it, it doesn't solve any issue (any more) that wasn't already solved in an easier way with fiat.
There's one exception: greater fool betting. That's the principal use of crypto right now, and that is something that will probably remain. It is an extra toy for gamblers. I already explained that there's no need to have a block chain for that: tokens as IOU on exchanges is good enough. With some extra law enforcement on exchanges, they can even be connected to bank accounts in fiat. You'd have X virtual coins A, Y virtual coins B, and people would trade them on the exchange. You can always return to your coupled bank account. No need to have a block chain for those coins. You hold them on an exchange, or you convert them back to fiat. You can couple the same bank account to different exchanges, and hence use your fiat to transfer "coins" (IOU) from one exchange to another. No need for block chain. And all taxes paid, all laws respected (the bank and the exchange check that). Everything known to the powers that be, as the law prescribes.
Why crypto then ?
By the way wake the fuck up.. everyone in Crypto is taking FIAT from their bank accounts to buy Bitcoin then to buy Altcoins like Dash or Monero on CENTRALIZED exchanges using picture ID for AML / KYC regulatory reasons.
Because "dealing with crypto on exchanges" is NOT using crypto ; it is just gambling on crypto. You don't need block chains for that, as I told you.
You may be right that what I propose is not going to work, but then, crypto doesn't work, period. It is like cars in railway stations. Yes, you can gamble on it. That's about it.
