Unless it spits out cash, there's still a centralized entity to get the fiat in hand. P2P is definitely an option. I could probably take a massive haircut to sell a whole bitcoin, in person, for cash in hand, but it's still extremely powerful. You can't do that with Apple or Tesla stocks.

Bitcoin is anarchy.

Bitcoin is disruptive.

Bitcoin is permissionless.

Trying to contain Bitcoin is like stuffing a marshmallow into a piggy bank. Good luck.
