> If everyone used the transit system to sleep in

Nobody ever does that, whatever a "categorical imperative" might be or represent. But not having benches because a victim of capitalism might, Heaven forbid, sleep on it, is the epitome of cultural and societal barbarism. Countries that do that are not part of civilized society, they might be wealthy, and many of them are (I've seen a similar philosophy in regards to benches in Switzerland), but they're not civilized.
