>>5105927because the only way you can prevent small groups of rich people + Government from enslaving you through the use of paid/fed armed men is by keeping the population armed and willing to literally fight against the rulers if they step too far out of line which they always inevitably do.
by giving up your peoples arms you're essentially dooming your people to enslavement for an unknown period of time.
im not too good at explaining these things but the point is centralized power is dangerous and history says that most Governments end up serving amoral ethicless undemocratic power so without a counterbalancing force (armed populace) they will always trend towards greater tyranny and oppression and will never let anyone free from their control.
