Not at all. I buy crypto through P2P, and I decide with whom.

This is not the experience of the vast majority of crypto owners right? How can it be a defense of anything if only very few people even use it like that.

Also, you haven't solved the question of middlemen. Now instead of mostly trustworthy Binance you would have to deal with the guy in the dark alley who pinky promises not to run away with your cash.

Not in Argentina. The P2P market is big enough that you don't need to worry about finding buyers/sellers. Also, "dark alley", here? Not even close. We've been doing this for several years now (used to be only USD), it's a well oiled machine.
