Your argument is "well if we could make the audience for PORN bigger it'd make more money." well... yeah, but.. morals? How does this compare equally to swapping out a jelly doughnut for a rice ball like the original comparison? This isn't questionable morality, it's localization.
Ask a Japanese person if dragonball is a kids cartoon. In my experience most of them consider it pre-teenage to teenager content. Kids. Maybe my definition of kids is too broad, but I remember watching DBZ when I was 10-ish along with all my elementary school friends. It's not like it was an entirely different thing than dragonball either, Goku is just bigger.
