Probably it's because that with government intervention on Bitcoin, this gives us the thought that 'yeah, they're supporting Bitcoin' but if we clear that path on the actuality is you're right. Many of us seems to unnotice what's actually happening on Bitcoin and they've got more control on it and can easily done than Monero. I just hope that purpose of Bitcoin won't be defeated and someday, we don't have to rely on these cexes and governments. But the truth is, this is inevitable for it as part of "adoption".
I don't consider that they, governments want and are doing it because they are supporting Bitcoin. They are doing this because:
They can not stop Bitcoin.
They can not stop their citizens to access a big innovation in human history.
So they have to create as many barriers as possible to reduce the adoption growth of Bitcoin and want to do more regulations to control financial flows in society. They are doing this to help central banks have more tools to trace their citizen financial flow and gain tax for their government.
Are they doing this for benefit of citizens? I see no.
