It doesn’t need perfect compliance to push down the R0 significantly. Lockdowns in the US are mostly not being strictly enforced, but enough people are complying to have a major impact.

I think economic incentives are also fairly well aligned here. If tests are widespread, a significant segment of the market is likely to prefer locations that are testing to those that don’t, just like the market tends to prefer clean restaurants to unsanitary ones.
