This isn't a unique idea. This is the mainstream view. Everyone knows we need more testing and that testing is the only way to effectively ease distancing rules. That was a pretty extensive writeup to say what we've been hearing from all rational information outlets for a month.
I have not found any mainstream sources that advocate screening everyone every day (which is very different from simply doing "more testing"). Would love some pointers if I'm wrong.
If "it happened and it worked" isn't "mainstream" then I don't know what is.
