If you study the scientific literature for works that measure actual infections with/without masks (and not hypothetical scenarios on droplet travel distances) you'll find that the science is far from being established.

Take a look here just how many works indicate no effect:

These may be cherry picked of course - no question there, still it is evidence that the science is not settled.

For a "home-run" review see the Cochrane review:

Not even N95/P2 respirators were found to be effective.
