Much like in the real world, those with power will need to voluntarily surrender it.
Luckily, I don't think our whales have had to kill anybody to get their power like their counterparts did irl, so maybe it could happen.

In the real world, not so much.
The only way to get people out that killed to get into power is to kill them, they've already demonstrated their limit is their life.
If your limit isn't taking their's, then they win, again.
And, they get to laugh at you like the 'lil bitch that you are.
Then they will rape your kids and grind their bodies into hamburger so they can sell it to the dupes as the 'heart healthy' alternative.

So, in the grand scheme of things, we got bigger problems than what some devs scheme up.
Could they have solved governance problems with this model?
Clearly not.
Could a different crowd do it?
Probably.

Will they?
Not without a proper leader to take point.

Ned could have walked among us as a god, but he wasn't mature enough to recognize that fact and was so spoiled by an easy life that he thought bringing a guitar to business meeting with his friend that looked like warmed over death would fly because he obviously could do no wrong.

You were here for that, weren't you?
