Covid-19 has proven similar to the common cold in transmission. The common cold is itself a corona virus so it makes sense.
Basically you are going to be exposed to Covid-19 at some point in your life. It's guaranteed. It's here to stay with the human race, just like the common cold corona's.
But there is value in delaying your exposure, even if you have little personal risk. Delaying your own infection also delays the infection of others (more vulnerable than you). They may be holding out for a vaccine. It avoids overloading a hospital. It gives the medical community more time to develop best practices and apply them to more people. If everyone gets covid-19 on day 1 then no one gets to benefit from the hard won knowledge paid for in death and damaged lung tissue.
Viruses tend to become less deadly as they mutate. Delaying your infection has value, even if it's inevitable.
