Can government completely ban Bitcoin or not? To find answer to this question one must consult Bitcoin Whitepaper, on very first line we find this:
"A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution." Bitcoin Whitepaper
Bitcoin was designed from scratch to overcome limitations of existing financial system, where every transaction has to go through a central authority for approval. Since there is no central authority in Bitcoin then how can it be banned ? Go through Bitcoin whitepaper and we can find answer that why governments are againest it and why it cant be banned.

Bitcoin was designed to be a decentralized and censorship-resistant cryptocurrency. It cannot be stopped no matter what. But that would depend on how far the community is willing to keep Bitcoin that way. If decentralization is compromised sometime in the future, you can say goodbye to Bitcoin for good. Remember what it's said in the real world: "The price of freedom is eternal vigilance". We must remain vigilant to protect Bitcoin from falling into the government's hands.
As long as it remains decentralized, Bitcoin will be able to reach the masses without any obstacles or shortcomings. All a person needs to access the Blockchain is an Internet connection (and a VPN if you're living in a country where BTC is banned like China). With how far Bitcoin has gone, it seems to me that it will last for generations. Just my opinion
