There are entirely practical reasons that "private decisions of adults" can worsen society as a whole. We need laws and we can debate about nudging that line back and forth, the answers aren't easy. But acting like there shouldn't be a line is nonsensical.

Acting like taking action doesn't have negative consequences is also nonsensical. There is a reason why we consider (Alcohol) Prohibition bad public policy. It was a complete disaster. Somehow those that wish to control others always forget this. These are literally the situations for which the phrase, "the cure is worse than the disease" was coined.
