The vision story of ETH is so sexy:

L1 as the world settlement layer, L2 as the world execution layer—everyone divides up the work and eats on schedule.

But the accounting can’t be ignored—L2 now uses EIP-4844 to compress data into blobs and submit it on-chain, pushing costs down to the floor. The settlement fee from L2 to L1 is almost negligible.

In other words, L2 is freeloading Ethereum’s security premium: enjoying the decentralized halo of L1 while siphoning the fees to itself and its users.

In the short term, this is the L2 flywheel; in the long term, it’s value leakage from L1.

If this problem isn’t solved, the financial model of ETH’s “deflation + security premium” will slowly be hollowed out by its most successful ecosystem. And the reason ETH/BTC can’t run is also here.
