The legality of many things which "do nobody any good" is part of living in a free country.
Didn’t say it should be outlawed, I just said it does lead some people to do ugly, unspeakable things that hurt not just them, but others as well. It has no redeeming social value (and no, self-gratification is not a social value, it is by it’s very nature a non-social value).
