The problem is that this is incredibly hard to do. It’s much easier to protect the vulnerable if the routes for community transmission are reduced or eliminated; if society is acting as normal it’s really hard to stop those specific transmission vectors. Given that we can’t convince people to wear masks, I’m dubious about any plan that requires more planning and communication.

We also have no idea if herd immunity will work, or for how long. Lots of coronaviruses confer either no immunity or a short term one; remember that a lot of common cold cases are coronaviruses too, and you can catch those repeatedly. Also, pursuing herd immunity involves infecting basically 20-50% of the population, a strategy that might kill 500k to 1.5mil Americans (assuming CFR stays at 1%, an optimistic assumption in this scenario)

We also have no idea what the health impacts for non-fatal cases are. Lots of patients are surviving with heart & lung damage; long term impacts TBD. Crippling an entire generation from the get go would both be tragic, and would put lie to the idea that not opening schools is “letting them fall behind”.
