You’re shifting the argument, which was about financial institutions in functional markets.

The argument is that cryptocurrency is useless under the assumption that the traditional financial market is functioning perfectly, i.e. that there is no regulatory inefficiency at all. There currently exist countries where this is not the case, so that assumption is incorrect and cryptocurrency is useful until such time as that is no longer the case.
This is assuming there is no value in regulatory arbitrage, which is wrong.
The value of this is proportional to the dysfunction of the existing system in any given country. In countries that impose currency exchange limitations or other authoritarian policies enforced through the financial system, cryptocurrency has more value.
You could capture that value by reforming the laws and governments in those countries, but that hasn't happened.
And one of the benefits of cryptocurrencies is encouraging those reforms. If you can't use the financial system to impose authoritarian policies because people will just use cryptocurrency instead, you might as well not try to use the financial system to impose authoritarian policies, at which point people can use the more efficient ordinary banking system instead of cryptocurrencies. But we're not there yet, are we?
