Because: if it is indeed only 50% for active virus detection.
then it will ALWAYS give a negative for a negative.
and SOMETIMES give a positive for a positive.
so still a useful coin to use in a population of millions as it could be all you need to keep r below 1.

I think it would work something like,
no syptoms + negative L.F. = carry on.
No symptoms + Positive= get a PCR test and isolate.
If you develop symptoms, isolate and get a PCR.
Regarding business model, these tests are less than £1 each to manufacture. So yes huge market
