What you call inefficiency (I guess in terms of power consumption) is a misuse of the term in a world where value is subjective. It is efficient and necessary for the use case and value it provides. You can argue it is ineffecient compared to Proof of Stake for example, but Proof of Stake is a completely different system and has a completely different incentive structure.
I’m saying also that L2 (and L3, … Ln) is a way to scale the number of users without increasing power consumption. Every time you add a layer, there are other trade-offs for the benefits gained. But at the base layer you still have the benefits of not having a central authority censoring and controlling exchange of an economic good.
