The most compelling reason I've heard, yet one I rarely use due to its complexity is about unrecoverable government capture. It goes like this: In the past, governments could be overthrown by internal revolutionaries or external forces. In the near future, governments will be able to surveil and anticipate their citizenry so as to make revolution impossible. They will do this because governments (political parties) have a self-preservation instinct. And with nuclear weapons in play, external overthrow is increasingly suicidal (excepting small countries). Furthermore, that internal surveillance department can be turned on the government staff itself, leaving a small group of (unelected) officials with power over the rest of the government. Eventually one of them will gain the upper hand. That means there could come a point of stasis, where governments become unassailably entrenched that humankind is stuck in a local maximum with whatever governments existed then. Let's hope our current dictator for life is beneficent.
