"Exists on the Web" means "has a URI".

"Exists on the Web" is condition in the Web Architecture's formalism 
that arises as a consequence of having a URI.  This condition's 
intersection with the real-world phenomenon of the same name is an 
interesting problem, but (I think) not one that we need to address.

Not at all.  This is a formalism.
