Everybody is in the risk group. (Nobody has any immunity.) Everybody is a carrier/spreader.

Many deaths have been people in the under-65 age groups.

Your system would lead to many thousands of sick people very quickly. That would 'heighten the curve' and overload the health system.

On the other hand, it would lead to a rapid spread of the virus, most people would get it very quickly. Some people would die, yes. The rest would recover and the wave of 'plague' would be over quickly also. It would pretty much be a copy of the progress of the Spanish-Flu pandemic of 1918-1920.
