>People can't hold power without the cooperation of everyone involved.
Following this exact same principle, people cannot overthrow a dictator without the cooperation of everyone involved. And doing so in 2022 (where dictators have access to fairly modern military tech and nukes) is not quite as accessible as it was during early 20th century revolutions.
Do what you will with that, but I can completely understand people not willing to "just overthrow the dictator, bro, it is that easy", when doing so would almost certainly end in their own death and the death of their family members (who had no involvement with what you did aside from being your relatives), all while accomplishing exactly nothing in the end.
Imo it isn't about "all normal people" overthrowing the dictator, it is about "big" people near the dictator doing so.
> "just overthrow the dictator, bro, it is that easy"
it's not easy - it's awfully difficult and risky, but it is that simple. Just like fighting Russian soldiers in Ukraine - it's not easy - but it is as simple as taking up arms and fighting.
Popular movements to overthrow tyranny (South Africa, India, etc.) have always relied on the masses refusing to cooperate or actively resisting.
