I think that we all need to figure out ways of carrying on with life as best we can, with the threat of COVID-19 remaining around for quite a while, and we need to continue to re-assess the situation as things evolve or degrade. I think hiding away completely, while banking on a future vaccine or the virus vanishing, is not really feasible.
The chance of catching COVID-19 seems greater in an area experiencing a hot outbreak, and less in an area that has no active outbreak. As long as each of us lacks immunity to the virus (through whatever means), the risk won't ever be zero and transmission only ever requires contact with a single infected individual, not thousands. The hand-washing and physical-distancing counter-measures are the only tools we've got right now, and the spirit of those guidelines are what need to be followed out in the community.
The other concern is the outcome of the disease for the individual if they do happen to catch COVID-19. That's the piece that nobody knows for sure ahead of time, but statistics to date indicate that the chance of a poor or fatal outcome from the disease seems to be higher with age (source: https://health-infobase.canada.ca/covid-19/epidemiological-summary-covid-19-cases.html)
Youngsters seem to be more willing to roll the dice on catching it, and it might be because they feel that their personal outcome would be less likely to result in hospitalization or death. Hopefully, those risk-takers are not mingling with anyone elderly.
