The most compelling objection (to me) is that when surgeons wear masks, they sneeze inside their masks, then change their masks. When everyday people wear masks, we take our masks off to sneeze, expelling aerosol virus particles into the air to be circulated in the A/C for hours (probably days). That said, some studies have shown a small effect of mask mandates on daily case count growth.
