I see wearing a mask as a short-term measure which may, just, help slightly slow down the spread of Covid . It is a minor issue- I wear one maybe twice a week for 15 minutes. I'm happy to do so as it might help a bit, it makes others feel better, and it doesn't put others (eg staff) in a possible uncomfortable position of wondering whether to 'challenge' me.
If it becomes compulsory 254 hours a day and goes on for months while infections fall to a trickle, i would agree it's an imposition too far, but we are nowhere near that stage and I'm sure never will be.
It's one of many laws, rules, requirements that some will regard as an imposition but is for the greater good- compulsory seat belts in the main, no smoking in restaurants/shops, no hand held mobile phones when driving, the expectation that you will not shop naked, not being drunk while driving- all perfectly sensible to the vast majority despite what O_G might think
