I think they can't stop the usage of bitcoin. The only thing that will make it stop is when they propose a law regarding the usage of the bitcoin. But, as long as there is no KYC needed in the transaction that you are going to do, it might take them several months to distinguish who made the transaction. They will have a hard time trying to identify who is who.
Stopping Bitcoin is almost impossible not unless there is a total ban of crypto trading worldwide but as far as I know that is not happening yet. And I don't think it will ever going to happen in the future but of course, the government can do anything what they want to protect its people. Although Bitcoin is not the problem here that's why the government wants to ban crypto trading, it is the scammers.
technological development cannot be dammed by anyone because it is clearly indeed what should happen, as well as with bitcoin because this is a technological product and cannot be blocked by rules that forbid it, because by prohibiting proving it cannot accept the progress of the technology. there is a limitation so that there is no misuse for things that are not true or misuse which results in many being harmed.
