I agree with you that governments globally know very well that they have many things to hide against their citizens and benefits of citizens as well. Bitcoin provides something different, transparent, traceable and beneficial so that governments will try as best as possible to prevent citizen's exposure and access to Bitcoin as much as possible.
Keep in mind that a Bitcoin Standard means the Governments have to accept a defeat against Bitcoin. No big Government would do that. It would mean the purpose of Bitcoin is fulfilled, which they hate. It is a very tough job, they rather create and use a CBDC instead using principles that at first glance seem similar to the ones of Bitcoin.
