If someone sees mask wearing instead as a joint effort to fight the pandemic, as means to get out of it earlier by limiting the spread of the disease or as a way that they can do something to protect themselves no matter what others might do, then it is absolutely not depressing. Self-efficacy influences mood positively a lot.
People here also walk around with masks during allergy season, or doing flu season even when they’re not sick. In Taiwan and Vietnam I saw (and wore) masks on days when the air was particularly dirty.
I suspect the Venn diagram of people who don't like masks and people who don't like coercively collectivist politics is basically a circle. It certainly is here in the UK, most opposition to masks in Parliament came from the Tory backbenchers which I guess is why their mandatory use was dropped this month; the 1922 Committee (a formal group of Tory backbenchers) can force a vote of no confidence in the Tory leader if 15% of them call for such a vote. Tory backbenchers tend to be more small-c conservative than the Tory frontbench, they're not necessarily anti-authoritarian but they're often anti-collectivist.
Not everything is politically motivated.
