Mao tse tung famously stated all power comes from the barrel of a gun. Is it then so difficult to understand why governments want to take your guns?

Mao cobfiscated guns, Hitler confiscated guns, Lenin confiscated guns, Castro confiscated guns, Pot confiscated guns, etc. Could anyone then fail to predict the industrial style and scale butchering of their political opponents which inevitably followed?
