Huh? Where do you live?
In the US, we have AREA code splits every once-in-a-while that result in
people's numbers changing. Also, the creation of new COs sometimes
results in a geographic area having its prefixes changed.
Yes, these events are not super-regular, but, they're a royal pain when
they do occur and adding network upheaval into that equation by mapping
phone numbers to prefixes seems like a pretty bad idea.
Also, if you move any significant distance, your phone number either changes,
or, you end up paying substantial fees every month for a "foreign exchange

You don't actually own phone numbers, either. They have greater (in some
cases) portability than IP addresses, but, you don't actually own the number.

Were that ability not somewhat fictitious, I might even agree with you. However,
since it doesn't actually pan out, the conclusions you draw from said assumption
also don't completely pan out.

Yep... Like I said, when they are forcibly changed, it's a major pain in the butt.

I'm well aware of this. However, in both cases, they can and are sometimes
changed at the instigation of the phone company and not the customer.
