Other people don’t exist for our entertainment or amusement. If a “not beautiful” person wants to be naked, that’s their choice.

Eh… a bath house != Bath tub

Bath houses still exist in Japan and a bunch of other countries. They don’t feel thaaaat weird after the initial shock wears off.

Externalized costs are a thing though. For instance, a coal plant spewing smoke (and radiation) costs everyone else money. A nuclear plant OTOH is usually responsible for dealing with all of its own shit. So it’s not always an apples to apples comparison to consider just the profitability of a project.
