Look at the revealed preferences. A grandparent might accept a 20% chance of dying, if it means regularly taking their grandchild to the park in the last few good years of life they have left. Most of the people at great risk of CORVID only have a few good years left. Or, look at things like obesity or smoking or drinking (all of which might be getting worse - will people develop bad habits in quarantine?). People are willing to take risks (and overburden the health system) over lots of things, and we accept that the government shouldn't make it illegal. Actually, why don't we just create quarantine safe old people's homes, and force them all into it? Then we can protect old people in quarantine, and let young people risk CORVID to build up herd immunity, then plunge the country into a brief elimination lockdown. It would be kinda inhumane to the old people we would be locking up (though people seem willing to take extreme measures anyway) but at least it would be quick.
