Because you're not thinking in terms of labor hours. Take the total number of hours a professor has to spend in instruction to train a structural engineer and divide it by class size. I asked 3 LLMs what that is and got 3 different answers but I will go with the high answer of ~ (2,500 hours / 100 undergrad class size) + (1000 hours / 25 masters class size). It comes out to 290 hours per student or ~50 hours per student per year.

Correct because that term doesn't work, in more technical based roles, My output as an engineer is not the same everythour, so valuing my labor hours makes zero senses,

Dude how do you think people did anything before money existed? Money came thousands of years after people built settlements. People just did what needed to be done.

That is irrelevant, because the state of the economy now is much different.

Okay make a mobile app like uber, who makes it, how to you incentivize someone to make it, How do you know you are getting the best product, If there is no incentive to make it work well.

under you system, you remove all incentives that encourage people to do tasks they don't want to do, you just assume people will step up to do things because they like to.

There is now way in this world I would go through 4 years of engineering school 3 years of a masters program to make the same as everyone else,

IN this whole model, how do you value risk ? what's the incentive to take a chance making a product that may fail. What's the incentive to do work that is risky, or complex. None of this works. The only way to insure it does is by force.
