I cannot comprehend a position of total long COVID denial, though I have encountered it online. Every virus you can think of that causes acute illness, can cause long term or even permanent damage. Sometimes rarely, sometimes often. Even the mildest common cold viruses, can, in very rare cases, be severe enough to cause pneumonia which causes scarring which leads to permanent loss of lung function. Hepatitis A is usually cleared without issue but sometimes significant liver scarring happens. The poxes can be cleared by the immune system but often immense scarring of the affected tissues happens. Viral meningitis...
For COVID to cause severe illness in a few % -- enough to kill in rare cases -- but to not cause permanent lung or heart or kidney damage etc. in some significant percent who got very sick is implausible, even incoherent with all other theories about how viral diseases cause disease.
