If they cannot generate enough profits to even justify holding on to the real estate rather than putting the real estate to some other use, is that meaningfully different from failing?
Essentially, it's arbitrage. "Can be arbitraged" is not the same as failing. You can talk about things like "efficiency", but the problem with that is that the metric being used to measure efficiency is laughably simplistic - deliberately so, it's just a way to justify socially irresponsible behavior.
