Unfortunately staying at home forever does more than zero. But that's just not a reasonable option. Not to repeat this as infinitum but R0 is a useful number to inform.

Killing cities of people to contain outbreaks achieve a lower R0, but frankly at this stage we're so far off topic of mask efficacy or reliability.
