Yes this will accomplish something, it pushes the peak of infections from 6 weeks out to maybe 10 weeks. Will that make a giant difference on the grand scheme of things? Maybe, though I don't see the hospital situation being drastically different in 4 extra weeks.
The point is that guy who got exposed a week ago and doesn't know he has it is still preparing your Chinese takeout, still stocking the grocery store shelves, still doing bank tellery things, and all the other jobs that are called "essential".
