Why recovered patients develop lung disease due Covid-19?

Now researchers in Hong Kong have said that recovered coronavirus patients can be left with damaged lungs.
A small study of 12 patients discharged from hospital showed that two or three had reduced lung function. However, it is too early to confirm any long-term effects.
"In some patients, lung function could decline by about 20 to 30% after recovery," says Dr. Owen Tsang Tak-yin, medical director of the Infectious Diseases Centre at Princess Margaret Hospital in Hong Kong.
Computer tomography have shown fluid- or debris-filled sacs in the lungs, which may get progressively worse as the illness develops.
What can determine the long term effects?
Why can this:
"In some patients, lung function could decline by about 20 to 30% after recovery," happen?
Are elderly more likely to this? or it could happen to anyone?
Does this only happen if you had severe symptoms?

The best theoretical model we have is that the SARS and SARS-CoV-2 viruses knock out the ACE2 receptor found on numerous tissues including alveolar cells, and myocytes, and intestinal luminal cells.
If those cells have died then they need to be replaced, and if and until when that happens there will be reduced organ function.
CT scans of recovered patients show some have ground glass changes pointing to extensive damage and scarring which may be irreversible.

This video by Kurzgesagt gives a good overview of how the COVID-19 infection process works. The damage it causes to the lungs seems to the result of it damaging the cells that create a protective lining of your lungs; this happens both directly as a result of their infections of these cells, as well as by causing the immune system to attack healthy cells. By killing large numbers of these cells, bacteria that this lining would normally protect from are now able to invade the lungs and cause issues like pneumonia. Additionally, the damage that is done during the initial phase can cause significant amounts of scarring within the lungs as the body tries to recover from the damage.
