Interesting that almost all of your examples of "contours of infection" are places that people don't need to go to, and the last one can be replaced by teleconferencing. That makes it sound easy: if you don't want to be tested, or it's too much hassle, just don't go there!
I assume in your system that everyone would need to be tested before going to work every day, because that's the most common in-person gathering for most people. The USA has run fewer than 50,000 tests in the months since this began. Your plan would require 100,000,000 tests in the USA every day.
No need to make the test stations "mobile". You could put 1,000 in every city, and they'd never have time to be moved. Every sidewalk downtown would be lines of people waiting for a test -- which itself would be a bigger gathering for me than just going to work.
