I agree. Also prevents Layer 1 bloat which should prevent chain size and chain growth from becoming issues that lead towards node centralization. Also depending on how further layers are organized applications can more easily hold state and data that is important and relevant to them while organizing other transactions and data in the ecosystem.

If compromises have to be made for the sake of scalability, it makes more sense to abstract those compromises away from the base layer rather than spend years undermining the base layers through updates and struggle to make any progress without introducing enormous amounts of complexity. Somebody is eventually going to learn from Ethereum's mistakes.
