> Twitter has the right to freedom of expression and freedom of association, and this gives them the perfect right to ban people from their platform if they don't agree with what people say

This is the legal analysis of how Twitter can do this, which I understand. But you keep asserting it as if it is some universal truth, without engaging with my actual arguments about the constructive result of such framework.

> a corporation cannot levy taxes, cannot jail people

Except that it can - you can sign a contract agreeing to some schedule of charges (called "taxes") or to have to spend time in a certain place (called "jail").

> cannot execute someone

The only reason you cannot sign a contract that allows for your execution as a consequence of default is because your bare ability to contract has been restricted by the larger government.
