I don't think that's how URIs are used in the RDF world.  It's not a 
matter of using an existing URL for an organization, but of creating 
controlled lists with specific meanings. I haven't ever seen anyone 
advocating the use of the URL that you list above. So, for example, in 
the library world, we will have an authority record for the UN and the 
URI that we use will be the URI for that authority record.
