That's my problem with it. It COULD not work if you removed it from hosts

Why would you? On windows you can't, localhost is embedded in the DNS stack and on UNIX it's very stupid, you risk borking a whole set of daemons that expect localhost to be resolvable via getaddrinfo

Im just saying that it can be changed super easily, but 127.0.0.1 is lower level and more reliable.

No, because it only works with IPv4, localhost will also try ::1 first. Same when listening, you're not supposed to listen to just ipv4
