I've read that you need about 40% of the population to be immune to it, for this to die down. Suppose you will inevitably get there no matter what we do (barring a deus ex machina like a vaccine) - you want to do it at a pace that does not overwhelm the health system. Another thing to consider is, that this is like a friction coefficient. So maybe if people spend 80% less time outside, we can maybe equate that to having 25% of the people already immune or something like that, and then 10-15% actual immunity is enough to make it die down.
