Great discussion! On the topics of incentive alignment between L2s and the L1 - actually based rollups might be the solution because in their case, Ethereum is basically the sequencer. The reason why rollups would go with a based roll-up design (or based sequencing) is that they can fully tap into the L1 liquidity without any bridging, and there can be direct interoperability. To make this happen, we need pre-confirmations and also lower blocktime on the L1.

Not all L2's are parasitic, the problem is in the Ethereum L2 incentives are not aligned at all....
