What lazy solutions will look like seems unpredictable to me. Suppose someone in the future wants to realistically roleplay a historical or fantasy character. The lazy solution might be to simulate a game world with conscious NPCs. The universe contains so much potential for computing power (which presumably can be turned into conscious experiences), that even if a very small fraction of people do this (or other things whose lazy solutions happen to involve suffering), that could create an astronomical amount of suffering.

Lazy solutions to problems of motivating, punishing, and experimenting on digital sentiences could also involve astronomical suffering.
Yes, I agree. More generally: the more things consciousness (and particularly suffering) are useful for, the less reasonable point (3) above is.
