I agree that those methods are beneficial and could also be applied in conjunction with masking. I am disturbed at the implications of your accusation. I can assure you I am not 'in the pay' of some shadowy organisation, and at a total loss as to what nefarious purpose any such body might have in promoting masks anyway, especially home-made and similar examples. If anything, notional 'new world order' authoritarian regimes would almost certainly want to avoid citizens covering their faces, as this could disrupt the identification of individuals in crowds. In fact, early on in Hong Kong's outbreak, Chinese authorities did attempt to ban mask-wearing entirely, due to the ongoing protests. Although some people were arrested and fined for the offence, the law was successfully challenged, and anyway the vast majority of their population had already begun wearing and in that city of 7.5million people there have been a total of four deaths over the entire course of the epidemic and they have now stopped publishing the 'R number' because it is incalculable with no new infections. Although some classes of businesses involving large crowds, particularly those indoors like cinemas, had to cease trading, there was no general lockdown and most shops and offices remained open. I have simply been convinced by the arguments of many rational people looking at international examples of how outbreaks were handled and am attempting to promote my understanding because I believe it is of supreme importance for public health. You are entirely free to disagree with me, but you are just one reader among many.
