Effect if L2 chains on ETH 2.0 and future pricing

I am trying to understand the pricing scenario for Ethereum on the long run. With the move to PoS, transaction validation is not much of costly affair for validators . So ethereum can run at much lower prices that today without causing issues for block verification.

Also with the proliferation of L2 chains, it doesn’t seem like there would be a huge demand for eth as well.

Unlike bitcoin, i am not sure ethereum has a goal for inducing scarcity to raise prices either .

So what are the thoughts of other on this . I like the direction ethereum is moving towards as a technology enthusiast. But i am not sure wether we should be expecting anywhere close to 72x growth like what ARK is predicting.
