If masks are useful: if people wear them, significantly more people are not getting infected or become unable to work and less people are dying. If they don't wear them, the disease spreads rapidly which ruins the economy more, and kills more people (yes, elderly and immuno-compromised count).
Without any proof of whether they are effective or not, it's still better to wear them as that's the best outcome.
