Anyone who wants to use Bitcoin as fully self custodial freedom money which acts as their medium of exchange can. The problem we face is not (currently) technical, it’s social. Very few people care enough or know enough to hold their own keys, much less run a node and verify transactions. I like the CTV model for further scaling in the future, but with that said, people are always going to be free to interact with Bitcoin through proxies. ETFs, Bitcoin banks, Bitcoin Visa cards, ECash, were always inevitable. Even if Bitcoin could support infinite transactions at zero cost, I suspect over half of the world would still prefer to use some form of bank or ETF wrapper. That’s not a knock on Bitcoin, it’s a knock on ourselves.
