Which government wants its people to remain poor? I don't think any country in the world wants that, Bitcoin is disliked by governments because it can't be controlled, unlike regular payment instruments (FIAT for example) which can be easily tracked and monopolized.
The government is sure that bitcoin or crypto is being used for illegal purposes that is why they are so keen on preventing it from spreading more and more people using cryptocurrencies. It’s a sloppy excuse because the real reason why they do not like crypto is because it is a threat to fiat. They lose control over the money and they lose control over the economy.
Don't underestimate the power of ideas. Who knows, there might come a time when governments would be led by people who are convinced that money should be made completely independent from the state.
We don’t know. One person will not be enough to turn things around. It will take more than that to deconstruct the system that most countries have been using to seamlessly turn to using crypto.
