Most of p2p was not running for profit. On the other hand, as soon as you interact with money, there are well-established means to control money flows. If the banking system stop interacting with crypto exchanges, much like they're banned from serving cartels or countries under embargo, cryptocurrency will essentially go back to the fringe status it had a few years ago.

That kind of regulation may actually be a good thing when it comes to blockchain operations, or at least the few of them that can actually demonstrate a benefit in isolation.
