Question about layer 2. Do layer 2s increase the value of eth?

I was just wondering if layer 2s increase the value of eth since their still using the eth system but also reducing the load of the layer 1. Do all eth smartcontracts increase eth value. For example shiba inu uses erc20 so does that mean the more people that buy shiba it increases the value of eth or am I wrong. Just looking for info thanks.
