It doesn't "scale" anything, the upper bound for Lightning channels is how many users can afford to unilaterally enforce claims with the chain, and that's purely a function of supply of Bitcoin
why would this be the upper bound when this is (by far) the minority scenario? unilateral exit is important to be able to exercise, but seems weird to assess the ability to exercise this in an extreme scenario that will never happen.
