An idea recently floated by some prominent thinkers in the Ethereum space to reclaim value for the mainnet is the taxing of its Layer-2s. The future of Ethereum does not depend on policy but on enabling frictionless capital movement between the L2s in question. Tariffing rollups may appear a neat way to reclaim value for the mainnet. In practice, it would fragment the ecosystem, drain liquidity, push users toward centralized platforms, and avoid decentralized finance altogether.

Liquidity fragmentation is Ethereum's real threat
In traditional finance, the link between fluidity and growth is well established. Lower barriers to capital inflows lead to higher investment. Take the European Union's pre-Brexit single market. Investment flows slowed when the United Kingdom's exit fragmented access to capital pools, as economists tracking cross-border activity noted. Ethereum faces a decentralized parallel.
Rollups, particularly those that are optimistic and ZK-based, impose delays of up to a week on withdrawals and offer only patchy cross-rollup liquidity. The result is a fragmented system in which adoption slows, and capital is underused.
