I agree that getting tested is sensible.
It is even more sensible when here is an actual treatment for covid, for vulnerable people, that is more effective if given early (it would be interesting to see more details on the guidelines for this). So there is even more of a point to knowing whether you are positive or not.
One really positive likely implication of having molnupiravir is that, if it halves hospitalization & death rates for covid, widespread use could potentially make the imposition of more severe restrictions on lifestyle far less likely (I haven't seen any press reports yet that really cash that one out).
So it made my day yesterday to hear about that, both because it is potentially lifesaving, and for the possible effect on society.
