And then there's a chance that you get revived into a world where you are in some terrible situation but not allowed to kill yourself. In this case, you have done worse than just dying.

That's a risk for regular death, too, albeit a very unlikely one. This possibility seems like Pascal's wager with a minus sign.

That said, I am nowhere near certain that bad future awaits us, nor that the above mentioned Malthusian scenario is inevitable. However, it does seem to me as the most plausible course of affairs given a cheap technology for making and copying minds, and it seems reasonable to expect that such technology would follow from more or less the same breakthroughs that would be necessary to revive people from cryonics.
