My (European) country did quite well so far, so from our point of view he would certainly seem overly cautious. People have much less fear than during the first wave. They try to live with the risk of getting infected by accepting that it is real, but not letting it dictate everything they do, which would make life more "surviving" than "living".
And I think that's a good approach! Within the confines of necessary precautions like wearing masks, keeping your distance, and banning big events, I think it is still possible to live a life which is worth living in a responsible way. After all, I also don't mind getting into a car while being fully aware of the risks (which could be worse than COVID's depending on where you live). So yes, I do think his recommendations are too drastic and also bad for your mental health. Next to that, most of them are impossible to realize for people who aren't lucky enough to be able to work from home etc.
Maybe I would have a different opinion if I was a US resident.
