"Bitcoin. Can't buy it out. Can't shut it down."

Doesn't matter. It can be completely prevented from being an medium of exchange - in fact it's incapable of scaling without any shenanigans at all - just by charging xaction fees, as was revealed in 2018. Not only that but it can be trivially bought out (but it won't, because that would enable stakeholders to profit immensely, and griefers won't do that) by fractional reserve banksters, and it can just as trivially be completely shut down by more means than you can shake a stick at.

Here's just a couple ways that I could eliminate the value of BTC tomorrow if I was king of the world: order ISPs to no longer resolve IP's of any exchange. Send jackbooted thugs to the doors of every identified BTC stakeholder and arrest them for something else. Firewall the internet so that international packets were only allowed if they went through my servers, and block all BTC. Shut the internet down, as in literally turn it off.

I've not given even a moment's thought to whether these are legal or not, or whether people would like it or not. If I did, I could still come up with more, that would be legal, and wouldn't get even one politician recalled.

Blockstream is a Bilderberger owned outfit. BTC is their baby. That's why you are allowed to have it. Cash fiat is the CO2 of money, and they want you to destroy it, because they'll make more money after you claim victory. Can you even imagine not paying taxes or fees on any transactions if BTC becomes the official currency of all nations?

You keep saying BTC, but I don't think BTC means what you think it means.

Edit:

"...greed rules the world."

No it doesn't. You don't even have any clue as to the value of actual interpersonal interactions, because you've never even considered valuing them financially. People put up with greedy bastards because it's more convenient than stabbing their severed heads on pikes. Actual decentralized individually owned means of producing goods and services won't make that happen either, because it'll make greedy bastards irrelevant, and the socially competent will just ignore them unless they cause enough trouble to make them worth putting down like rabid dogs.
