Not in your post, if you did you could quote an actual rebuttal that larger populations don’t inherently need more food, increase the need for banking services, etc etc.
You also found it odd I didn’t “remove non participants” but preindustrial societies didn’t necessarily have formal jobs for people. You’ll note I didn’t exclude modern stay at home parents as non workers because labor is the metric not if you have formal employment.
>Ignoring for a second that net jobs and employment rates aren't really the same thing.
Net Jobs can increase while their percentage of all jobs drops. These things aren't necessarily linked or related. There isnt really a built in expectation that banking for 10 million people needs 10 times less staff than banking for 100 million people.
Demand scales with population, if the average person talks to a bank teller for 10 minutes a month having 10x the number of people doesn’t lower that number.
If automation doesn’t cost jobs, then growing the population shouldn’t change the overall employment rate meaningfully.
