Here's the thing some people still haven't grasped (maybe even those who seek to control it). Bitcoin is permissionless.

While this is true, they can't stop people using it for P2P payments. The only thing stopping this becoming widespread is the number of people willing to accept Bitcoin as payment.

There is no dollar value massive enough where this becomes false.

There's no minimum number of Bitcoin in circulation required to trade with it.

Productive people must be willing to exchange their time & materials for it.
