From what we've seen over these weeks advisories simply don't work, and although most of a population usually comply with sensible measures there will always be idiots that fulfil some need through non-compliance. In this case they 'announced' a 'requirement' to wear masks with no penalties for violation.
Much more effective and likelier to save lives, imho, which is the real name of the game and never mind hurt feeelings, is to motivate the people like those nasty totalitarian regimes do it, with incentives that actually work; ie wear a mask if you don't like jail, or don't go out you might get shot.
