For some reason, the word "productive" causes some readers to get the wrong message. (I.e. some readers see a blog text mentioning "productivity" and thus it must be some veiled guilt-shaming article.)
People don't try to be productive just for the sake of being productive. People want to improve their lives and productivity is a natural focus of optimization to bring about a quality-of-life improvement.
Your pushback is similar to previous commenters that rejected the idea of "productivity" and I replied in previous comments

To recap one of my comments, even the prehistoric hunter "having enough to eat" is not fine because the hunter still wants to improve the productivity of hunting. Over the last 10000 years, people have continuously improved the productivity of hunting (and farming) so much that today's people like you and I have enough free time to type HN comments -- instead of spending all day chasing after animals to eat.
People naturally want to improve their lives. Some people also want to share ideas on how to improve their lives. It seems the word "productivity" has tainted that discussion. However, it doesn't change the fact that people still want to reduce the ratio of effort-to-benefit.
"instead of spending all day chasing after animals to eat."
Actual working hours in small hunter gatherer tribes like the Lakota were more likely around 3-4 hours.
Medieval peasants had to work all day long.
But both experienced starving in winter and spring, in a bad year.
So I see this point as being evidence to GPs perspective, rather than your own, respectfully.
Doing something that makes you unhappy even more because you do it more efficiently doesn't make you happier, only more efficient
I really ought to remember to write a list. Oh wait I have one, where is that tab again?
Procrastination can be the thin end of the wedge though and, in extreme cases, deciding not to do things develops into doing nothing, like not going to work, not paying paying bills, not opening letters or answering the phone, and so on...
To a degree, mass media undermined that foundation.
