If the property owner is fine with it then that's ok but in many cases there has obviously been no permission granted.

If this kind of thing is allowed to happen then it opens up a slippery slope, that's all. Laws are not subjective. People only think this is cute because it contains the word 'smile' but if he was doing the exact same things with the word 'asshole' or something, there would be a completely different reaction...even though the exact same laws are being broken either way.
