I call it bitcoin, and I think it is scaling as much as it needs to through L2s. I think lightning and liquid will both go through some evolution before they actually see widespread use, but that evolution shouldn't require changes to the L1. I don't see any issue with bitcoin's present fungibility. Last I checked, my bitcoin was still free of banks.
I think our only point of contention is whether or not it is reasonable to make changes to an L1 based on proposed needs for an L2. I say it is not.
