Actually, there are a lot of similarities. Take the G rating, for example. You may log on and wander around for hours having a perfectly G-rated experience, while off in some obscure corner someone's having mudsex in which all the sexual terms are replaced by the word "smurf". As far as I can tell, this is in every way similar to the case of players exchanging items for money on a no-money-accepted MUD.

The point I think KaVir is making is that the only destination reachable using the logic you're employing is that we can make no categorizations whatsoever. Since we have already decided that we will perform categorizations of some kind, your logic is something we cannot employ and preserve our purpose.
