I kind of agree with his philosophy. Isolation delays or lengthens out the pandemic. In addition and probably a very important part of what he is saying is that people aren't building up immunity to it as a society, so, the situation might be just as bad subsequent years instead of getting the majority the antibodies to be immune to it going forward. I see that point as well. It's a balancing act.
I wonder with the other historical pandemics how many years they actually affected the population, like the Spanish Flue, Bubonic plague, Hong Cong Flu, etc..
Found this which is interesting:
