I'm not confused. But you are introducing unnecessary concepts here. A firm needs to make some profit in the long run, whatever you want to call it, to be able to sustain investment. If there's too many firms in the market, that can be undermined. That's why you don't see five dry cleaners right next to each other in the same strip mall.

And your second paragraph fails to address my point too. I acknowledged that in the long run, the health of the industry could be restored by some of the firms failing. But that can take way too long, and in the meantime, all of them are capital-starved and unable to invest in improving their businesses.
