You want to know the essential difference between an anarchist and a statist? I'll spell it out for you, in three easy-to-digest, mirrored sentences:
Anarchists care more about doing what is right than about the limitations of our individual imaginations.
Statists care more about the limitations of their individual imaginations than about doing what is right.
Not seeing how it would work for every tiny issue does not make it morally acceptable to rob, kidnap, cage, kill, or extort others.
Not seeing how it would work for every tiny issue scares statists into suspending their morality in order to rob, kidnap, cage, kill, and extort those around them to ensure they get their way.
It's wrong to do those things, no matter our fears or insecurities.
Even though it is wrong to do those things, they will do them anyway, because of their fears and insecurities.
