You're spot on. (at least I think so, and it's not just because I've been saying similar things all along!) As well as everything you mentioned, and the domestic violence Torbs mentioned, let's not forget routine medical procedures / screenings that were either never done, or postponed past their effective dates. Some things need to be caught early in order to be effectively treated. And there are probably many, many other things that are worthy of being mentioned in the same category.
When the total cost of human lives lost is tallied up for the less than effective lockdowns, it will likely dwarf the number of those killed by the virus. And that's just those who have or will perish. The mental health issues you mentioned, for those who have had their livelihoods ripped away because of this, is probably not measurable.
The financial costs are easier to calculate, and are IMMENSE. But the final nail in the coffin, so to speak, is the item from the produce section now occupying the white house. Trump was well on his way to re-election when the libtards and their propaganda arm (aka the media and big tech) jumped on the situation with the virus as the only way they stood a chance of taking down Trump. And now we have a demented vegetable for a president, who promised to get the virus under control, but has no clue about how to do it.
