What drives eth price?

Yo, guys, I have a question. From what I understand ETH price is driven by gas fees and how much all the smart contracts and eth transactions require gas. But if in the future some feature gets introduced that lowers gas fees will then ETH price drop as well since you dont need as much eth to execute blocks for on chain activity? Or how does that work? Please, I would like to know what will drive ETH price in the future with all the scaling solutions introduced and what even is the list of things affecting eth price in general? I understand that its supply and demand, but where does the demand come from? Why wouldnt eth price drop if most of the transactions move to layer 2 where fees are really low?
