Sometimes government is always the hindrance for the people to have a good and prosperous life. They just want to own everything, cash, gold and now bitcoin but unfortunately they can't control the decentralized digital currency but they still have the power to regulate or ban it. It's sad because you already have your own banks in your hand but government try to steal it. Bitcoin is more than fiat because it can be an asset and also a currency. Without banks, you can use it as your own banks to save money and to make transactions with your own without third party participation.
They don't have the power to ban in, but they can make it hard for people to use it or own it in a lot of different ways. What I think though is that forward looking governments haven't really been cracking down on cryptocurrencies, but rather tried to embrace it more or less. See a few countries in Europe are very pro crypto when it comes to their policies and even in the US the jury is still kind of out, but they haven't destroyed all hope and positive expectations for cryptocurrencies yet. I doubt they will and plan on doing that. The US is the big tech country and those familiar with crypto in the US expect their government to make the right decisions. There are also representatives fighting for good legislation, I am optimistic it will all pan out positively for us.
