The blade is still moving very fast, it doesn’t stop spinning. The guard is what makes it safe - though maybe there are other types out there?

Pretty much any circular saw made in the last twenty years has a brake.

  • Yes, but braking is not instantaneous. IIRC, the blade will spin for 2-3 seconds (instead of possible 10 without any brake).

    It's possible that the guard would close faster than the spin would stop.
