I think you seriously under estimate the public health crises that can be caused by not being cautious.And I wouldn't be surprised if more advanced were made regarding vaccines or medication that helped those people.
There's being cautious, there's being overly alarming.

Latent effects from COVID potentially affecting an entire generation of youth in their later years could complete collapse a health care system.

All the energy and anger people have been channeling against government measures need to be channeled towards industries and practices that increase the likelihood of another pandemic.
People have been far angrier about restrictions than the meat industry, for instance which, according to many scientists, employ practices that will engender another pandemic.
Our whole current situation is caused by the selfishness of humans, and we continue to use our selfishness to justify a quick return to normalcy, a blaming of institutions trying to help, while ignoring practices that may result in something much worse down the line.
