I also purposefully did not insult the commenter's character, but restricted my reply to the comment itself.
Indeed humans provide very little energy. I've always used this to understand the value of oil to our society. Value, not the current price! :)
A barrel of oil fed into a machine can replace the work of hundreds of laborers. In this perspective, oil is ridiculously cheap, alternatively viewed, it provides us with a lifestyle that is luxiurious and some feats that are otherwise impossible (transoceanic flight).

They are not "trading their body's energy". They a performing a task which requires innumerable inputs, among them energy, vitamins, oxygen, correct ambient temperatures, training, tools, etc. Energy has a preferred fundamental status in physics but it does not have such a status in this economic transaction. There is no reason to emphasize over any of the other inputs. You are bringing it up because of the aura attached to it in in physics.
I didn't get that out of the original comment, and wouldn't presume to apply intent. I think most learned professionals here understand what is meant when they hear or say (for example) "that task took a lot of energy" or "I spent a lot of energy doing xyz..." without having to spell it out in academic terms.
More reasons to think your comment is more about making the reader feel the insight is deep: there are other important conserved quantities in physics like charge; shouldn't that play a foundational role in economics if your analysis was correct? Will you next say that business leadership is really about "taking charge"?
