That doesn't follow. You're going to have this problem with any
naming scheme.

Not at all. You just can't make the assumption in an open system
that a URI is always being used to refer to the same resource
across the system. Ambiguity is going to be a part of a system
where anyone can say anything about anything. URIs are very useful,
but care needs to be taken when merging data where URIs are used as
names.

Yes, let's impose order on those people...or maybe they'll impose
order on us. Anyway you do realize that eventually cars will have
IP addresses and very possibly URIs?
