We already have a almost universally in-home now, cheap, reusable screening test but it gives too many false positives and false negatives:  A thermometer.  

The idea of a trivially cheap test procedure that can be done at home is appealing but I'm not aware of that test existing.  When it exists, and is cheap enough, and accurate & sensitive enough, then we can potentially be in better shape.   (But I bet the same people that are having backyard BBQs for groups would not be using such tests either.)

Personally, I'd rather have a cheap-enough sensor for the doors of businesses, like the anti-theft sensors, that identifies someone shedding virus as they walk by it.  I'd preferentially do business with such stores, knowing that the likelihood of encountering the virus was lower there.  I don't have to trust everyone that I encounter actually took & paid attention to the home test.

Heck, we don't even have a system in place to isolate those that have tested positive or to quarantine those that know they were exposed.  If I were working at my place of business, how would I know if the person that cleaned the area didn't leave virus around?  

I'm still waiting for my Jetson flying car.
