Aside from the fact that you may spend a week or more spreading virus all over the place and to potentially dozens or hundreds of other people with this approach, there is at least a 1 in 10 chance that, if infected, you will need hospitalization and serious care. You will contribute to overloading a medical system, without which even your mortality rate would be closer to 5% than the <0.1% you seem to assume. It is simply not the case that this has no effect on the non-elderly; severe pneumonia is a debilitating condition even for the young and fit. For a large fraction of everyone who gets it, this is WAY harsher than any flu you have experienced, and even many in your demographic will need extended hospitalization.
