I think you still do.  You own the URI but you don't own Paris.  What 
people gets back is your personal "impression" of Paris.  If other 
people don't agree with your impression, they cannot use your URI to 
denote Paris.  They have to mint a different one.  Whoever gets right 
will be shared by more people, other URIs will die.  This is the rule of 
the game.

A URI should denote one and only one thing. But the converse is not 
true.  A thing can be denoted by many URIs, but we hope it is denoted by 
only one URI.  URI owner and resource owner are not necessarily the same 
one. As a matter of fact, I think, most time they are not.
