you can't ban bitcoin, the same way china can't stop users to access facebook if they really want to.

Your government can say it's illegal, what prevents you to cross the border?

If you study enough and know how to manage your private keys, Bitcoin is the only asset that you can really own, no one can take it from you, no one can prevent you send it to someone else, or receive from someone else, even if some gov want to have their piece of cake when you sell it, you may take your own decision to do the best for you.

You can acquire bitcoin without kyc on bisq, robosats, and other options, and slowly but surely, more and more shops/coffee/bar accept bitcoin as mean of payment (at least here in EU)
