The mask doesn't prevent the spread, it just slows it. Look at the data from the various states about the effectiveness of lockdowns and mask mandates, they had a number of total cases per capita, they just had a flatter curve.

Pushing for masks made a ton of sense in the first couple years of the pandemic when hospitals were getting overrun, but wearing a mask today doesn't really prevent anything. COVID is already endemic, so the best you're going to do is increase the time between infections a bit.

When I got COVID last, I was on vacation and had to get home, so I tested myself as soon as I was able, self-quarantined as best I could, wore an N95 mask when I couldn't, and put off unnecessary trips to the store. Once I had recovered, I went back to not wearing a mask. That's how we should treat it. I do the same for colds, the flu, etc. I'm not wearing a mask unless I'm either sick or likely to be directly in contact with those who are at risk.
