I don't know where you got this idea. It's certainly not true.

SMTP isn't so restricted. You can send and recieve email to/from ANY
server anywhere on the internet; no password required.

SMTP & POP are meant to solve different problems.

SMTP is a Mail Transport system. It's designed for moving Mail around
the network. It was designed in the good old days when everyone who
had the tools and knowledge to forge email had reasons for not wanting
mail forgery to work. It's primarily used for sending mail between
peer computers of various kinds. High-end implementations don't ever
depend on some other computer to touch the mail, unless there is data
in the internet-wide hosts database (DNS) instructing it to do so.

POP is a Post Office Protocol. A host in the SMTP peer network acts
like a post office - it collects mail from other SMTP hosts on the
internet and holds it until the POP client comes to collect it.
Likewise, it will accept mail from POP clients for delivery elsewhere
on the internet. Since POP was designed for use in hostile
environments (your local university network, for instance) it includes
user identification and authorization features. POP (2; I haven't
checked 3) always depend on talking to an intermediate host that is
filling the role of the Post Office to deliver mail. From the above,
it appears that POP3 can deal with multiple mail servers and use any
of them as the gateway if required.
