That sounds more like a profession of faith than a logical argument. But to refute, kiddie porn is banned and not at all powerful. In any case TOR is quite thoroughly compromised by multiple law enforcement and related agencies, so maybe that particular pirate cove isn't your best bet.
Why do you think they can't ban it? If they can regulate it they can ban it. Use of an illicit currency would be a financial crime that they would investigate like any other.
Then how are you free from "corrupt governments"? You're still paying taxes on income and on property, so even if you acquired property with funny money the government is still getting its cut. And if the government felt like crypto was getting out of hands it would apply further laws to it or outlaw it.
Ah, I see, you think that because you can mint Schmecklebux or whatever and use it as a medium of exchange, you're somehow exempt from the laws of whatever country you're in when the trade goes down? Tell me, does your flag have a fringe on it?
All money is fiat money. It has an agreed upon value outside of its intrinsic worth. If you want to get away from fiat money you have to go back to barter.
That is the zoomerest shit that ever zoomed.
