Talk about sewage... It is 100% accurate to say that the finding of viral RNA in wastewater indicates circulating infectious virus in the community. There is nothing suspect about it except I suspect you don't know what you're talking about. You in your greater wisdom could perhaps explain to me how genetic material from Covid gets into the wastewater if there is no Covid in area.
Fourth, you are wrong that masks made no difference. The data, and there is lots of it if you want to do a GoogleScholar search, showed masks did work, just less well than hoped. The failure to find greater efficacy is because of people not wearing masks correctly, and human nature to not practice good hygiene, hand wash, social distance etc. even when mask wearing.
Lastly, you are correct that some viral strains tend to weaken over time, that is sadly not always the case. If it were then we would never have a more severe influenza season. We would never have seen SARS or MERS. Polio would have disappeared without a vaccine... and measles... and ebola... and etc. etc. etc.
