As soon as COVID is over we're out.
In a few years when vaccines have been found, 85% of people inoculated and no more proven Covid-19 cases have been found for 30 days?
or...?
But if we could halve the death-rate or more, it'd be pretty good steps towards getting back to normal. Also, if we could actually get people to wear masks and take it seriously. That'd go a long way towards quelling it.
We'll obviously need to accept some level of risk to do that, unless we're willing to wait for vaccines or herd immunity, as you pointed out. But it may well be a year.
I wouldn't be surprised if COVID pushes a lot of people to be nearer family.
