Exactly. For personal protection you use n95 or better and know it’s not perfect. If you don’t care about personal protection but want to reduce spread in a community then getting large groups to wear any face covering will help, but not nearly as much as social distancing which renders masks meaningless. For community spread, again not personal safety, it’s best to just stay home altogether. Masks are like pulling out during sex, a very imperfect way to compensate for bad behavior (not social distancing).
