No. For most of human history we've been lead by shitty autocratic leaders. Now, when there's too little to go around we're more apt to go to war and/or have population migrations which is a different subject.

If only it were that easy.
I don't know about "only", but I agree that that's the best move: Fewer labyrinthine dependencies, more providing directly for yourself and your neighbors.
But isn't the difficulty of that proposition a direct function of population density? If "locally" means 1000 people on 100 acres, that's a lot different than if "locally" means 10000 people on 10 acres.

To put it differently, premises:
1. The planet can sustain 100M of us
2. The planet cannot sustain 100B of us
3. There is uncertainty about whether the planet can sustain 8B of us
Conclusion:
The safer direction for our population to go is down.
If it's clear that there's plenty to go around you can just abandon a bad leader. If not, then maybe tolerating them is a necessary evil (because they control the food).
