Yet historically, it's not true that free speech implies anything should go. There's good reason for some restrictions. Libel, slander, lies, disinformation, etc. - all sorts of speech can cause harm or significant risk of harm. Free speech is an important right, so any need for limits had better be darn well established. Good intentions alone (moral guardianism included) are insufficient. Some slopes really are slippery.
Mmm, I think I did answer that, if I'm understanding correctly. The desire to improve your appearance is, as far as I can reason at the moment, intrinsically linked to a concern with what others think about you. Vanity, validation in the eyes of your peers and significant others, even self esteem are connected in some way to how you believe others will judge you, whether you choose to rationally acknowledge this or not. So yes, for most people, physical appearance may well be in a category apart from physical and mental self improvement.
There might be a few other tangential reasons, but they amount to "if you've got it, flaunt it." You could use your attractiveness to further your career. I can't help imagining all sorts of horribly sexist (and unethical) scenarios though. Sure, if you're going to a job interview, don't look like a slob, but that's just being pragmatic. Emphasizing your sexiness for a job interview is questionable behavior, even if it gets results - perhaps especially if it gets results! I suppose models and porn stars do have to make a living, but uhh... we were talking about sexism, right? Yeah. Exactly. Where the heck was I going with this? Tell me.
So I'm still not sure of the purpose behind your previous reply. Impressing a mate ought to encompass reproductive urges. I don't understand what this business of guaranteed pregnancy is supposed to be about.
