Are you under the impression that a book can't be found stating the opposite. Also, could you give me the page numbers in that book that specifically address what I said previously? I mean you wouldn't simply be posting a "basic economics" textbook so that you could lazily state something is wrong without forming any type of fact based opinion.
I can't speak for where you are at, but where I am people are voluntarily doing this themselves. I am not seeing a lot of pushback except for online message boards. For example, I was trying to purchase some weights from a guy from craigslist (they are very difficult to find right now, even from online retailers) and he texted me and said that he wasn't selling them right now due to the virus. Perhaps there is more pushback is less densely populated areas that haven't been hit with the problem yet.
