Instead of a name of the form:

...you just use a name of the form:
name + "." + vocabulary-name + "." + domain
The same varying information is in there, so it's exactly as unique.

Again you're confusing HTTP URLs with URIs.
Using URIs as identifiers allows lots of identification schemes other
than HTTP, in particular ones that are not based on DNS, or that use
DNS, but include a timestamp to address the concern of "losing" a domain
name (tag URI scheme).
