I think governments have a lot of problems now (Covid-19 pandemic, economic problems, unemployment, etc.). 

Bitcoin is the future.  Governments understand this.  How to ban bitcoin in this situation?

Banning Bitcoin will generate additional interest in it.  Bitcoin is not the most anonymous and confidential cryptocurrency.  If Bitcoin is banned, people may be interested in other, more anonymous coins (like Monero). 

Therefore, governments have chosen a different path.  They are waging war with Bitcoin through laws and regulatory restrictions.
