Do you think bitcoin will stay if government totally remove their hands or stand against it?
Unless Bitcoin crashes, which is likely not possible. Bitcoin will live on, and as long as Bitcoin lives on, the government cannot be able to totally stop Bitcoin in every part of the world. For instance, the US government can decide to stop the usability of Bitcoin by citizens in their country, but they can't enforce such a law in other countries, and if the government in those countries is not against Bitcoin, users in that country will not be affected.
Check your lexicon as regard to the meaning of crash in the cryptocurrency vocabulary. Bitcoin crashes and has crashed so many times, but after each crash it still takes up to bull market.
Yea, since there is no central government in the world, the governments of the world would never agree and speak with one tongue. While the government of China bans bitcoin and bitcoin related activities, the government of the US will adopt bitcoin and verse vice.
And also, government as an entity might be against bitcoin but the individual persons that make up the government might be involved in bitcoin in one way or the other. So bitcoin will last as long as its chemistry permits.
