The problem with the “love it or leave it” argument is that it is circular.
The statist is trying to prove that government is justified. Then they assume that government is justified, and say that you can leave if you don’t like it. So they just assume what they are trying to prove.
In other words…
1-Government is justified
2-If you don’t like it, you can move to a different country
3-Therefore, government is justified.
That’s statist logic for you!
