What you call influence is simply trust that others impart to an individual. There is very little a single individual can physically do by themselves. So if there is someone with the influence to challenge a militia then it's better to say a proportionate number of people are also challenging the militia with the person as their proxy.

This is the argument populists make regarding Caesar, and there might be some truth to it, but it falls apart when you look at a Venezuela or North Korea; it’s easy to say that a nation gets the government it deserves when you aren’t the one having your life threatened.

Then again, outsized influence is a problem in democracies as well; this is what creates the conditions for a Caesar figure to emerge in the first place.
