Even if everybody could, they wouldn't because they are immersed in a culture that celebrated consumerism at every instance. You can't just turn a switch and now you live self-sustainably.
And yes, I agree with your second paragraph. "The culture" celebrates it — but that culture is not violently enforced top-down by a handful of people twirling mustaches. We all participate in our own little ways — and the more of us that step off the treadmill, the less those messages find footing, in a virtuous cycle. Again, it's not about blame. But for those of us who have the capacity and desire to decondition ourselves, it's very much worth doing. It can affect the feedback loop more powerfully than we think.
Everybody is quick to jump the gun and blame the victim, while all this can be easily explained by the insane lifestyle we are forced to subscribe in order to survive in this crazy cut-throat productivist job market.
If "all the clocks are wrong" it doesn't matter as long as they are consistent. (in the case of atomic clocks, frequency of energy transitions within atoms)
All ntp servers get the average of atomic clocks, which is then distributed to all phones and computers.
If the constants from these atomic clocks "are a little bit wrong" it does not matter (for most human activities)
That's why we average them and distribute the average.
For physics related research, this new clock being more precise does have use, but for pretty much everything else, whatever constant we have is good enough as long as it's consistently used.
Back in the day it was someone just running around with a pocket watch giving everyone the time from the clock tower which was calibrated from a sundial and that was good enough.
Replace the sun's shadow with electron transitions and the timekeepers with ntp servers and that's what you have today.
it's a human construct so whatever is agreed upon is correct.
