Um, you *are* aware that we had a global telephone network *before* we had
computers, right?

Tell me. When you (or your boss) needs to talk to someone in America, how
do they do it? What steps do they follow?

You ... haven't picked up a phone lately?

Exactly. It doesn't map cleanly to the global network that was already
around for decades before IP was even conceived. It is difficult to manage
and debug and route compared to the world-wide telephone network everyone
takes for granted. And they're running out of addresses (actually, probably
already ran out of addresses) long before every person has an address, let
alone every piece of communications equipment.
