It's no contradiction at all. How others live can and does affect my quality of life. People living in community have the right to ensure that the bad actions of a few do not degrade conditions for everybody else. Thus, a community may pass laws against people having sex in public, or public intoxication, or playing ultra-loud car stereos in residential areas.
The things you mention affect you so I agree. Now I must assume you have no problem with personal behavior as long as they are done in private.
You are not entitled to happiness.
Only to the right to act unrestrained in pursuit of it, provided your actions do not violate the rights of others.
Try looking up the definition of the word "commune" sometime you friggin' socialist. You don't even have the decency to deny it any more, do you? I've suspected you of being a democrat plant for some time, this really takes the cake.
Every one of these is a public issue, not a private one, and as such I don't think most sane small "l" libertarians would have a problem with reasonable restrictions against it.
Where we have the problems is when people start trying to outlaw private intoxication, private sex, or playing the stereo too loud on your 10 acre property ::grin::
