Fairly definitively that was always the wrong answer.
In the future:
1. Most people will get SARS-CoV-2 antibodies from their mothers
2. Early life exposure will happen
3. The SARS-CoV-2 virus will be force to make expensive mutations to avoid immune escape will come at a cost to fitness.
None of the conditions can be created by what you suggest. You have the problem of having the relatively most-lethal / most-transmissible version of the virus spreading unhindered in a population of >40 year olds who have no natural immunity. The "COVID party" solution maximizes the death and cost of the virus.
