And that's the kind of innumerate thinking I don't understand. Masks aren't an either/or thing. Say masks are maybe 60% effective (there's no real consensus and good science is hard to come by). A mask-wearing vaccinated person is now 96% protected. Add that to staying outside (maybe another 75% or so?) and you get to 99%. Every bit helps, which is one of the reasons why we're reaching herd immunity.
Now, you're right, there's a cost tradeoff. If everyone is at 99% it would be pure insanity to close restaurants, say. But... masks? Leave them on, until it's dead. Again, this is the cheapest mitigation we have. Roll back every other protection first. Send people back to the office. Open up the stadiums. Start hugging again. Lift the visa restrictions. Visit the grandparents. Do all that stuff first before relaxing mask use.
