Not having a central single governance is the whole point of the exercise, it's a trustless system driven by mathematical rules and decentralized consensus. You can't stop a transaction, you can't kick anyone out (good or bad), the rules can only be changed by decentralized consensus and certain rules are pretty much guaranteed to not change (for example, any Bitcoin chain that has more than 21M Bitcoin issued wouldn't be called BTC, it would be treated like a fork, etc).

> It's pretty wild cryptocurrencies are still legal in many parts of the world.

I think there's a few reasons for that, one is, it actually makes money (ex: Coinbase generating billions, tax money generated from all the capital gains, electricity paid for by miners, etc), capitalist systems won't ban money making machines. It's also impossible to ban, you can ban on/off-ramps, you can't ban Bitcoin from running and transacting, by banning on/off-ramps, you'd lose any visibility into what's actually happening on the pseudonymous network. And last but not least, if this ends up being the next big thing, nobody would want to be left behind, so there's some game theory mechanics as well.
