> Everyone in the world masking (with effective masks), distancing a bit, and using standard sanitary practices edit to add, because I forgot - for two months, and a few with immune compromises spending some more months isolated, would eliminate a significant chunk of all contagious respiratory illnesses, not just have stopped this single one from spreading.
This is delusional. China did far more than this and still was not able to control Covid. And even in a fantasy world where you could actually stop all human-to-human contagion, many respiratory viruses have animal reservoirs, making the entire exercise pointless.
It's comforting to think that it's all just a collective action problem and if people could be a little more self-sacrificing, we could make it go away, but it's simply not the case.
China is not the whole world, and had to deal with the risk of COVID entering the country from other places. Notably, they did bring COVID numbers down to a very low level, albeit temporarily.

None of this contradicts GPs claim that it would eliminate a significant chunk of all contagious respiratory illnesses. Quite a few (common) respiratory diseases don't have animal reservoirs and would be effectively eliminated.
And I didn't mention the problem of people who can't afford to take precautions, which is why this is a collective action problem.
And sure, SARS-CoV-2 did end up in animal reservoirs, but nipped early enough in the bud this either wouldn't have happened, or would have been controllable (with respect to animal-to-human transmission).
