So forget breakthrough infections for a second.
Covid has both pre-sympomatic AND asymptomatic transmission. This has been proven.
In many places, a negative PCR test means you do not have/carry the disease and can participate in risky activities. The NFL, and the NBA, did this. Movie studios did this. Australia and New Zealand did it as a whole country.
To do that, you need a very sensitive test, not something that only confirms symptomatic infection.
Of course, a very sensitive test has more false positives. But you have to weigh that with the possibility of an outbreak among those who tested negative. Imagine what would have happened if NBA had an outbreak after PCR tests--"The Tests Are USELESS!" the media would say.
How many false positives? Look at how many players sat out during the NBA bubble.
Now back to breakthrough infections. The CDC's thought is that vaccines protect well against existing strains, and their guidelines follow that assumption. Nothing in their guidelines accounted for the Delta, though they are changing their stance now, but slowly.

But you have also take into account that these are not just numbers. But these are numbers that can destroy countries and communities by implying perpetual lockdowns. It becomes even more comical that RT-PCR does even when positive, does not imply presence of the virus, but some fragments of a dead virus or even genetic material of some other viruses. I can only be appalled at the indifference of these people to mandate lockdowns that destroy lives and businesses, based on positivity rate of such a test.
