No, that's not gonna be happen. We all know that government was categorize in centralization system while Bitcoin was categorize in decentralization were obviously the government can't able to control bitcoin because of this wonderful and great features of bitcoin.
I don't agree with you. It's the goverment we're talking about here that means that they have the power and the permession to do it if they have to. They can hide the sites that you can talk about or buy bitcoin from, they can confiscate mining machines. But, the only reason that holds them from doing this is that bitcoin is no danger on the economy and used by few people around the world.
