You're arguing as though "better testing/tracing" is an amorphous goal that keeps moving, when people are actually talking about quite specific and quantifiable goals. For instance, in WA:
"The recovery plan begins with widely available testing for individuals who may have contracted COVID-19, tracing for those who have come into close contact with COVID-19 positive individuals, and isolation or quarantine for individuals who could transmit the virus..... For the contact-tracing plan to work, the state needs to be processing between 20,000 and 30,000 tests a day."
