So to put things in a short form, if long covid is real (and it looks to be, we know covid does damage, and there is research showing persistent micro clots in some people)
Personally I think there are a good number of people who have pre-existing conditions they've not been to a doctor about for various reasons using long COVID as a way to get medical attention - a lot of people don't like going to the doctor for various reasons whether social anxiety, embarrassment, or other but long COVID is a kind of more generally recognised thing.
Having had COVID and seen how it can attack other organs though I don't doubt there are people with all kinds of long COVID - if I'd not started to get better when I did even a couple more days would have likely seen serious long term damage IMO. If the infection went to say someone's kidneys (which it is capable of), etc. and was more than just mild it could have all kinds of consequences through to a long term debilitating condition.
