There's nothing to stop people using crypto to buy/sell goods directly, or to trade directly between themselves, completely outside of government control. And crypto itself can't be inflated away, or obsoleted, or otherwise really controlled by government, except by attacking it; making it illegal to own or trade, to operate nodes, to write code, or use CIA shenanigans, etc. But if an exchange claims that they hold your crypto 'frozen' and completely separate from their trading activities, and especially if the exchange also deal in government currency, then I think it's quite right for government to regulate, and ensure the exchanges are compliant.
