And the fact that he was able to gather his troops and move them without issue to the border of Middleton points toward him having actual control of his territories. That he lost and was subsumed back by the government is not really argument against him being ruler before it.
If he is CEO of Megacorp and said Megacorp is basically owns a state (provide food and manage taxes) then he rules it. The more power corporation gathers the more indistinguishable from the local government it becomes. Unlike other CEO Doof is just being somewhat honest (if only for the wrong reasons) about it.
Perhaps his claim of total independence is somewhat questionable, but him being ruler of Tri-state area is not wrong. America's government ability to overthrow him, does not make him not ruler. It can do it to other actual rulers too.
There's a difference between ruling and having incredible influence over. Fundamentally, Doof doesn't get involved in affairs of 'state'. He doesn't deal with the criminal justice system, or make actual laws, he just exercises his power when he wants to and mostly gets his way.
That is definitely real power, and it is especially concentrated in the Tri-State Area. In fact, people in there like him. But they don't consider him their ruler, merely 'their guy', in a sense. He doesn't actually get paid taxes in any real sense- 100% of what's sent to him goes directly to the federal government.
The local government is very clearly a distinct entity, even if it doesn't want to move against Doof. It acts on its own, not as part of the megacorp, it's just utterly beholden to the megacorp.
Pretty much. The one other being who shows the capacity to do some of the things Doofenshmirtz is able to do. Only, Doofenshmirtz is not omnicidal and is actually a pretty nice dude? So the comparison falls kinda flat l, after all.
Fundamentally, I do see where you're coming from. I personally have some anarchist leanings, after all. But the problem is that Doof doesn't actually have the capabilities that Cipher does, and secondly that 'no rules no restrictions' doesn't actually make sense? Sure, you can minimize rules, you can keep everyone immortal and having fun, but you also need to prevent them from hurting one another.
Now, do you, strictly speaking, need a government for this? Maybe not, maybe you can rely on self-governance and acting in good faith, for the most part. But even if Doof was thinking of that (which he's very clearly not, by the way. He wants no rules on him, not no rules on anyone), he just doesn't have the social capability to manage such a thing, and sticking to his delusions won't help with that.
Fundamentally, I'm not even saying that Doof should stop helping people. Heck, he can still help people in ways that might make the government unhappy, I'd find that fun. I don't want to be a number go up optimizer. But claiming something incorrect out of pride doesn't actually help people. All it does is make it more likely that he won't be able to help people, and keeps him stuck in the past, instead of being able to help/rule over people properly.
