I think it's only true for Countries without free health care or free health services like the U.S.. Switzerland doesn't offer free health services (so some people have to pay fees). But I just googled it and it says the government reimburses them. So I have no idea why she would like that post. It doesn't apply to her or any other country with decent healthcare.
Oh wait. I just googled the doctor who's post it is, and he is an Irish doctor who closed his practice because he was threatened with suspension for spreading misinformation. There seems to be a theme for where she gets her information. It's not even that he thinks masks don't work, he was claiming that wearing a mask is dangerous.
