First of all, actually America is a place where people ARE refusing to wear masks and follow proper protocol. At certain rallies and marches (I don't want this to get political but this is taken place against that backdrop and landscape), almost no one wore a mask or complied with protocol. There have been places (college campuses, beaches, large family gatherings etc) where people have partied maskless leading to COVID outbreaks. I certainly would not use that as an example of people following guidelines. Also, in many cases, there are examples of countries NOT following their countries "medical people", as you put it, professional recommendations. It's hard to be able to "see this out" when your recommendations and guidelines are NOT adhered to.
Second of all, I'm the one that used the argument that Anna (and Sasha) witnessed what Evgenia went through during the Olympic season and partially because of that this has become normalized. That was my argument. (I suggest rereading my comments.) I used it to defend Anna and say you can't single her out when there are numerous examples of skating through serious ailments and Anna (and Sasha) would have seen them up close. And they made an impression on them, undoubtedly. (As a side note, we don't actually know if Evgenia thinks skating through a broken foot at Rostelecom was worth it. Evgenia also withdrew from nationals that year so I doubt she would blame Anna for doing the same same. I certainly think Anna would look Evgenia in the eye for doing the same thing, in this case withdrawing and that (2018) was a more crucial year, as it was the Olympic year. This year we don't even know if Worlds is happening. Do you also think Aliona can't look Evgenia in the eye? How silly.)
Thirdly, Anna herself said she did NOT know if she could do it.
Finally, we'll address the departure of Sasha and Aliona. First of all, Anna is NOT them. Second of all, Plushy despite knowing all this DID take actions, although I think not enough. He DID pull Aliona from RusNats despite her just having arrived to his rink. He didn't cater to her wishes, even though by your logic he clearly should have. Keep in mind too that allegedly one reason she left was because she couldn't get her 3A back at Eteri's rink. Well, she still doesn't have it back (no fault of her own, I might add just continuous bad circumstances) and he STILL pulled her from RusNats. He ALSO got Sasha to limit her program content. Despite knowing that Sasha herself said she left Eteri's rink because they limited her quads, he coached Sasha (due to injury but nonetheless) to limit her program to "just" two quads. I believe even with injury, Sasha would have still wanted to do more.
A coach that caters to their students wishes without making decisions and taking responsibility for their skater's well-being is NOT a good coach. (That applies to ALL coaches.) If Eteri did not withdraw Anna BECAUSE she's afraid of Anna leaving then she ISN'T a good coach for Anna (or anyone). (If Eteri didn't withdraw Anna because, with the medical information she had available, she believed it was "safe" for Anna to compete here and she would not endanger her health further, that is a different story.)
