Domain Name System was an app on the Internet. It wasn't something that always existed. The purpose of it is to provide intuitive means to look up IP address from more intuitive domain name strings.

If you could come up with an alternative system to derive the IP address of desired remote host, or content, e.g. Magnet Link standard, you can just skip DNS and switch to that instead.

TLS can be a problem as a lot of moving parts of WWW now depends on DNS. But all of those can be solved.
