A power grab by who? Mask manufacturers? People who don't like to look at lips? I am baffled by the belief that asking people to wear masks, in the middle of a pandemic, is a power grab by anyone.
If anything, an intervention that would make it safer to open up more businesses and public spaces should be seen as a great thing for reducing the power needed to shut these spaces in the first place.
I wasn't specifically referring to masks, but now see that the thread had gone that way. I would say, however, that doing good and grabbing power are not mutually exclusive.
I, too, am baffled by beliefs (in general) and would suggest any new powers given to authority be viewed with extreme suspicion and of limited duration before enacted.
Everyone is grabbing for their own power, for their own reasons; they feel this tailwind but they assume that it means they're right, not that they're temporarily useful to other parties with their own agendas.
