Well the current peg-out arbiters are centralized exchanges, DEXes, and other systems. The value flows from BTC to other places where you can use your money in other ways. None of those systems are contributing much if anything to BTCs security budget. In drivechains, they would. All of the market cap and fees from Ethereum, monero, and other BTC competitors could be contained in the BTC ecosystem.

Instead we have the current situation where there's more BTC wrapped into Eth than there is on the lightning network. And lightning has no way to scale to 8 billion users because every channel requires a utxo.

All while we fight over the "right" way to manage L1 instead of letting different options compete simultaneously and letting users choose.
