It's an admission that the scale at all costs people can't quantify the risk/reward of their proposals.
Reality is there's no scale ceiling anywhere in sight, we can literally open more Lightning channels in a year than there are combined businesses and households on earth.
So what do scaling people want exactly? Pathos. Scaling panic generally sniffs out to left-coded cope that Bitcoin isn't more divisible, that Bitcoin must be bad money because it doesn't solve inequality.
But Bitcoin cannot be more divisible, not without a consensus hardfork to a unit other than sats. Hense the recent wave of L2 proposals are scams that appeal to Pathos: "you're a bad person who wants people to stay poor" if you dismiss it.
