because they don't get anything from Crypto, the government only needs money, without money they will refuse anything even if it's good for their country.
people in government like money and I agree that crypto is not interesting for them - they can't touch taxes from it)
There are things that are greater than taxes, that is decentralization, when the use of crypto is increasingly massive, it will make the government powerless when problems occur, everyone will turn to crypto and this is dangerous for legal money.
