If they ever discuss it I dont think they can full control bitcoin, not saying about the bitcoin, the transaction thing they will sure hard to think any solution for this because there are more people trading everytime its like 24/7. And are you sure that the creator of bitcoin want to cooperate with government? I dont think they will because they barely know who is the creator of bitcoin
We can't underestimate the government just like that. They can do anything for earn very high profit for them. If the creator(s) of bitcoin won't cooperate with government and make them feel be annoyed, they can block all of bitcoin website, even shut down our internet access. What would we do if that happen? Well thats just my opinion
