I think you are cognizant enough to appreciate that there is no they, ultimately, there is just us, imperfect as that might be.
I see it this way. The primary goal of the vaccines is to save lives directly, by offsetting morbidity associated with infection. A secondary goal is to save lives indirectly, by making as big a dent in community transmission as possible by reducing infection through a combination of sanitizing immunity and acquired immunity.
The data that the CDC is supposed to release tomorrow, from what I've seen of the slides floating around online, shows three main things. Nothing really unexpected but I expect a continuing public relation disaster. First, delta is very infectious. The range that's been floating around is R0 5-8. It's probably at the high end of that. The messaging will be "infectious as chickenpox". It's important to realize that maintaining sanitizing immunity levels of neutralizing antibodies (ie any infecting virus particle is simply preventing from binding its receptor) to that sort of virus is really challenging. Second, the data will show that, despite this, the vaccines still provide really good efficacy to susceptible people. Efficiencies still in the mid-upper 80%. In the real world, that's a good vaccine. The third thing is the bad news, which again is not necessarily a surprise for anyone paying attention. Given the titer of delta, vaxxed/infected people can (and the key here is whether the data is all vaxxed people vs "breakthrough infection" people) appear transmissible as non-vaxxed people. These are issues there a bio-stat person needs to look at and undoubtably are. But on that secondary criterion for a vaccine delta may simply be too much. For reasons i have outlined previously, i hope the guardrails stay on long enough for there to be a pediatric vaccine. Now that the FDA wants a larger size for clincial trials (reasonable) that will be delayed; late fall maybe. At that point, however, we will have had the luxury (with Iz paying the penalty) of allowing people to make their decisions. We should then let CoV-2 burn to ground/equilibrium in this country as quickly as possible. In some parts of the country it is probably already doing that.
Bottom line, you may get your wish. Although we are talking about re-implenting passive measures now, if the vaccines can't reduce the R0 of delta those guardrails may come off sooner rather than later. No masks, no shutdowns. If you aren't directly affected, you might not notice. Others will.
