Apropos my suggestion that even libertarians might allow some regulation of offensive behavior in government-run spaces, simply because it's offensive, what do people think about laws banning public urination? As best I can tell, urine is usually mostly sterile. Sometimes it's not, but I suspect that on balance public urination is probably no more of a public health threat than, say, sneezing without covering your mouth. (Assume that in either case you're not urinating or sneezing directly on someone else.) It's banned, I think, largely because it smells yucky, and (less importantly) because it's perceived as yucky even setting aside its smell.

If I'm right on the public health point, does it follow that laws against public urination are improper?
