Maybe we need to take a longer term view? Further ahead, more people will have had the virus and gained immunity, or there may be a successful vaccine.
In those circumstances, I think humans, as a social species, will be desperate to resume normal social interaction, including the pleasures of restaurant meals, convivial pubs, coffee shops, holiday travel, etc.
And the vast majority of younger people do not face any great risk from the virus even now - over 99% of them would survive an attack of it. This may mean they are keener to socialise than vulnerable or older people.
