Politics is not exactly the art of philospohical consistency.
"We need to ban guns, and we give certain people the right to use guns in order to enforce gun bans"
"We prohibit theft, and we will give a few people the right to steal most of people's income, which is then used to enforce our laws"
"Slavery is the worst thing that can ever happen to a human being, but we're gonna lock children up in education camps where they have to do work every day because that's just necessary for society"
