One of the interesting speculations we can make about space travel is that off-world colonies will experiment with different political arrangements. Sooner or later, the political systems they bring with them will be shown to be inadequate to the new conditions, and they will try something different, not that this means it will be necessarily better, or the transitions peaceful.

If you have a lot of systems, just as many are bound to be worse as are found to be an improvement. And just because a system allows a colony to survive, or even prosper, does not mean those living under it will like it. Feudalism is stable, durable, easily administered, very robust
and ensures some measure of prosperity, security and justice. But it can occasionally erupt into war and it depends on enforced servitude for the many for the benefit of the few and their children. And the few will always claim that that servitude is the price that must be paid for their enlightened stewardship.
