There is plenty of proof of long term and potentially permanent side effects, including some that are uncorrelated to disease severity. It's also true the relative prevalence of such side effects is far from well understood, but that is not a valid reason to dismiss the concerns outright. To counter your statement regarding "no evidence", here's just a few recent studies that provide such evidence (please note that this list is extremely far from being remotely exhaustive): 1) https://academic.oup.com/brain/article/doi/10.1093/brain/awaa240/5868408 https://academic.oup.com/brain/article/doi/10.1093/brain/awa... "The high incidence of acute disseminated encephalomyelitis, particularly with haemorrhagic change, is striking. This complication was not related to the severity of the respiratory COVID-19 disease." 2) https://www.nature.com/articles/d41586-020-01891-8 https://www.nature.com/articles/d41586-020-01891-8 (on the possibility that C19 may trigger diabetes) 3) https://medicalxpress.com/news/2020-07-physicians-comprehensive-covid-effects-lung.html https://medicalxpress.com/news/2020-07-physicians-comprehens... (on the systemic effects of C19, many of the acute complications have chronic effects detailed in the full study if you care to read it) 4) https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)31094-1/fulltext https://www.thelancet.com/journals/lancet/article/PIIS0140-6... (on Kawasaki-like autoimmune disease in C19-infected children) 5) https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(20)30222-8/fulltext https://www.thelancet.com/journals/lanres/article/PIIS2213-2... (post-C19 lung fibrosis) Note that I've only cited evidence from highly cited and peer reviewed studies. There's a lot more if you care to follow the medical literature, but I think I've proven my point. 7 months is actually extremely little time for proper epidemiological studies on long term complications, it will take years to understand the prevalence and relative risk factors. What is clear, however, is that there is plenty of clinical evidence for different kinds of long term complications that necessitate further research.
