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?

MAC address is like your street address. 42 Wallaby Way. It’s hard to get directions with just that information. There can be multiple (vendors try to eliminate this per geographic region, but it happens).
If we go with IP, now it’s more like a set of directions for the routers to the MAC. Go to Australia, Go to Sydney, Go to Wallaby Way, Go to 42.
