Right now many governments want to join the crypto world and want to adopt it on a large scale because they can't beat Bitcoin for real, they can only scream, Slowly Bitcoin has become a real target for the government in investment & trade, in the future of course they will join and declare Bitcoin legitimate as a digital currency for investment and trading tools.
I wouldn't go as far as saying many countries are itching to join the cryptocurrency industry or that they want to adopt Bitcoin so bad, if they wanted to then they prolly should have done that a long time ago. When you say they (governments) can't beat Bitcoin, you have to understand that it depends on your own definition of "beat", definitely there is no chance in hell that governments can completely ban Bitcoin worldwide, but a specific government can ban Bitcoin in her country and make it illegal, they can regulate it sternly, control centralized exchanges and stop their banks from processing transactions from crypto exchanges.
Having said that, if we are tbh, too many governments aren't interested in Bitcoin just yet, the decentralized nature of Bitcoin makes it unattractive to them, it would be difficult for many governments to make something that they can't control a legal tender, thus it might take quite a long time for mass adoption to happen.
