- Have many smaller states rather than a few big ones. If there were 10,000 states and a worldwide culture of allowing freedom of movement, then you wouldn't have to worry so much about your state falling to tyranny or mob rule, since at least one of the other ones should still be OK.
Well this is actually never going to happen, if you would have 10,000 states, I find really hard to believe those will allow freedom of movement. The main trend would be populism and being constantly afraid of people coming in and "stealing our women and jobs"
The solution to that problem is relatively simple; be more of a benefit to the target state than a hindrance if you wish to move there. Unfortunately this is easier said than done for the majority of people.
The fall-back is to work to make the state you are stuck in be more close to the state you like. Or move to a state who will have you (and others like you), and where such an evolution is a realistic possibility.
This may sound like 'open borders' from a mile-high viewpoint, but it not. The basic goal of 'open borders' is to make all states the same and eventually glue them into a single uniform entity. Such a thing will be very much more easy and very much less expensive to control and manipulate.
