Medical personnel also have training to not touch their face, wash their hands repeatedly, and use disposable gloves.

Standard people do none of these.

N95 masks are useful in two cases: 1) medical personnel with training and 2) people actually sick so they don't cough it onto others.

For normal people, N95 masks have significantly decreased effectiveness since they don't cover your eyes.

N95 masks are utterly wasted on sick people. They prevent stuff coming in, not stuff going out.

The training needed to use the mask properly is basically ‘make sure it closes properly’ and ‘don’t touch the fucking thing unless you wash your hands afterwards’.

Seems fairly doable for the general population.
