Your claim is that growth is bound by the law of thermodynamics because of human labor?

Is your claim that growth in human population is required for economic growth?

Ok, I'll do another proof by contradiction using the chair analogy:

The carpenter uses the materials that would have been used to build 100 chairs to build a boat. That boat is then used to transport goods up and down a river. The economic value of that boat is greater than the 100 chairs but the carpenter has not done more work and they have not used more materials.

If all the human carpenters switch from creating chairs to creating boats you can get economic growth without using more materials or labor.
