I would identify everything (even people with a new URI schema).
I would locate with URL all what is possible to reach from the network.

I like your examples.

My opinion: YES.
Even if you don't want an URL for a person
(it would be not a web-locator because a person 
is not on the web, and would be difficult 
do deal with a geographic locator: people move), 
you might still want to identify them with an URI.

Typical example: you want to write metadata in RDF 
about a person.
I think you need an URI.

What do you think ?
