If you can't follow how dumb your own logic is, then I'm sure you can't follow my logic.
If you base a nation/organization/whatever on coercion, it is, de facto evil. It's really just that simple.
If you can't steal, then it is not right for "the government" should not be allowed to do it, either. Any attempt to justify evil is naive and anathema to any consistent moral position, unless you're ok with evil as being "moral."
Don't bother trying to say "that's an oversimplification. The real world doesn't work like that." Well, it has, and mostly isn't because of inconsistent, immoral people like you accept those base evils as "necessary." Evil is moot necessary, and saying it is is just disgusting.
