Right.

This is the tricky bit. I've had enough conversations about this to
achieve a kind of understanding of the "there's no difference between
names and locations" school of thought. Well, I think it's a kind of
understanding, I could just be confused in different ways.

The sequence of characters "http://site.org/resource-i-want" can be
viewed as a name. Just like I could change my name to Cheyenne Wyoming
if I was so inclined.

The problem is that naming something (other than the city) Cheyenne
Wyoming is just begging for trouble. You're going to have all sorts of
conversations like this one:

Random Person(RP): What's your name?
Cheyenne Wyoming(CW): Cheyenne Wyoming
RP: No, I didn't ask where you live, I asked what's your name
CW: I told you, Cheyenne Wyoming
RP: Yeah, I got that, you live in Cheyenne. What's your name.
CW: No, you don't understand, my first name is Cheyenne and my last name is Wyoming.
RP: Really? Man, that must confuse everybody.
CW: Yeah, just about.

Similarly, the string 'http://site.org/resource-i-want' looks exactly like
an address. So why call it a name? Why confuse things so much?

I dunno. I don't subscribe to that school of thought.

But the semantics of a URI is not always a location.
