Abstract spherical cow thought experiments can be difficult and still be abstract spherical cow thought experiments. What makes this completely irrelevant to anything I care about, is that "many shitty lives" vs. "few high-quality lives" aren't options that exist in a void. Whatever complex worldwide system you're talking about that would put those two choices on the table would have all sorts of massive side effects, and those side effects matter in deciding which is preferable. It's just not useful to discuss it in some hypothetical infinite blank frictionless flat surface where you've arbitrarily decided that having a baby later is murdering the potential baby you might have had earlier. That's not reality and it has no impact or relation to reality.
