Don't be fooled by the YouTube people because most of them saying all these craps and against bitcoin and this isn't something new. It is left for you to believe or not and come up with something from your head instead of saying what you heard from other persons. Bitcoin has advantage than its disadvantage which has made it the best assest to invest on due to its volatile nature. And you told you that government can buy all the bitcoin when they don't even know how many people have bitcoin in their wallets. Mind you not everyone will sell to the government because bitcoin is better than their fucking fiat currency that depreciates. I will rather keep my bitcoin than exchange it for fiat. How will the government buy the bitcoin that would be mined in 120 years by then the government that planned such would have died,so this can't be possible.
