> Perhaps if you think the government (people) shouldn't have power to "intervene", you (a person), or another group you approve of (yet again people) also shouldn't have power to "intervene" either?

People shouldn't have the ability to intervene with my life choices or property. Government guarantees that others don't do that, but uses its monopoly power to intervene itself. To some extent, I would prefer if it were individuals trying to intervene, because individuals are far less powerful than the government. For example, the government can forcibly search me before I board a plane, but if the government weren't doing that, and only some airlines were playing security theatre, I could simply choose an airline that decided not to waste my time.
