L2s are the most sustainable block-selling businesses possible (with current tech standards).

The economics are simply too powerful for any L1 to compete with, including Ethereum.

An L1 cannot compete with a system that doesn't require issuance and safety quorums to sell blocks to users.

I've stated this many times in the past, L2s are the future of blockchains from a first principles perspective.

The role of an L1 in this picture is to serve as a source of truth for the co-existence of multitudes of L2s to settle on. This is the only long-term sustainable business model for an L1.

Ethereum is the only chain making strides in this direction.

In the long run, it will be so obvious that optimizing for L2s is the correct path to depend on.

Path dependance matters, and Ethereum is on the right path.

Cardano is about to be a layer 2 for Bitcoin, with limited supply and onchain governance. We shall see how they pair.
