Is a f(r)ee market.
If on chain transactions go to 1 sat traffic for on chain settlements will rise. And when fees go back up, pressure to use second layers will go up again.
This is how the market finds its balances. And ultimately how bitcoin scales.
This is self correcting. Is the difficulty adjustment for the human side of bitcoin. And since its humans we will try to game it. Nature of the beast. But free markets well always find balance.
