Would more governments do the same because Cryptos threaten the banks
The danger for that to happen has passed. Governments understood that they cannot fight it, so now they started embracing it. Some can already pay their taxes with Bitcoin, after all.
I don't think that banks and crypto would be agreeing with each other, but it still depends to some countries. My bank recognized Bitcoin and that's it. I can deposit Bitcoin to my bank account through 3rd party app.
Banks and crypto don't have to "agree", they (somewhat) compete each other after all. But in the same way a bank accepts USD and EUR, it may accept Bitcoin too (someday).
We are moving in that direction.
