I'll give mine to get the ball rolling.
There was a user that, before getting banned, declared that every single living human being alive on Earth right now should not exist because no one had the benefit of a pre-conception device on hand to somehow determine each individual's consent to exist before they started to exist.
I don't know if that take would make David Benatar blush, make David Benatar cackle with glee, or if that was posted by David Benatar himself.
Even with all of that aside, pipes leak. Pipes rupture. A pipe that long has a staggering number of points of failure all the way to where it's going, and not all of them would be accidental.
California doing less bazinga shit with water like golf courses and rich asshole amusements would matter a lot, and also less almonds and alfalfa crops, but...
Then their answer would be something like "but under communism we'll have better pipes that don't leak"
Communism is about rich assholes in California getting to keep their golf courses.
