you have no reason. if you enjoy your life and do not want to foment anarchy, then don't.
if revolution breaks out you may be eliminated, along with the rest of the class enemy, though.
Oh, so now you're threatening to wipe me, my family, and my peers out if I don't embrace anarchism? I don't care, myself. In fact, I dare you to bomb my house if that's what you really want. Seriously, as though I'm going to be afraid of such a threat.
there is no moral reason to support anarchy. whether you gain or not, there is no need for you to support anarchy at all. as an aside, most anarchists don't hold moral beliefs anyway.
Oh really? If someone offered you political power or wealth, would you turn them down? If you said yes to that question, then you do in fact have moral beliefs of some sort. What do you call a requirement to abstain from the trappings of the upper class if not a moral rule?
