I’m aware that the mac address is part of the data link layer, but why can’t I just use my MAC address as IP address, too?
Why do I need both addresses?

A MAC address is your legal name. It’s who you are and isn’t easily changeable.
An IP address is a nickname. Some people call you Frank, some people call you Frankie.
Depending on what router (friend group) you’re with, your IP (nickname) will differ.
