collapse of the old society

That's what democracy is trying to do.

On the other hand, as I said, no state means a feudal state. If rich men or organisation are not reigned in some way, they will seize the power for themselves. It is actually what's happening in liberal countries.

With more cynism it is how societies work: an armed group seize a place for its profit or comfort. Until it's submitted to a more powerful armed group. Democracy arise when the armed group want peace from the people under its rule. Or when the people are the biggest part of the army and get to organise themselves to take over.
