Masks work.
Some people just won?t ever understand science.
Masks work more than zero. A cloth or blue surgical mask isn't doing much to reduce the transmission of an aerosolized virus. The virus is about 6 microns. A cloth mask has about 60 micron sized pores. A properly worn N95 or KN95 mask is your best bet, but even those have pores large enough for aerosolized covid to get through.

There's a cost/benefit element as well, but that ultimately comes down to the individual's beliefs. No sense in discussing, no one is changing their mind at this point.
Covid is now endemic and a part of our lives for at least the next few years. Nearly everyone is going to get covid at some point. Taking measures to reduce the severity of the inevitable covid infection is where effort is best spent, which means considering vaccination and geting your body healthy with diet, exercise, vitamin D, and the guidance of your physician to address your specific needs. Treatment options are also needed to address severe cases and long haul covid. Obsessing over case numbers, masking, distancing, mandates, and villainizing people who disagree is an exercise in futility.
