Basically, if you or a group say "I'm in control forever because I've always been in control and my goal is to always be in control forever.", at the very least, your reasoning on why you have to be in charge has no bearing on whether you being in charge is good for people, effective at the tasks of governance, or even objectively good for yourself.
A similar argument to what you're saying would be, "Ford makes the best cars because they have been making cars the longest." It's demonstrably false, to use your words.
