I dunno, I don't think we, as a society, should be prioritizing the health of the old and infirm over the health of those that are young and healthy via policy.

The CFR statistics in that graph are misleading anyways, confirmed cases early on would have skewed drastically towards more severe due to lack of widespread testing. Similar arguments can be made for large spikes later on as the ability to get a confirmed case can dry up due to demand for lab tests.
