> a human to draw something will require more water.

That human would require the same amount of water whether you ask them to draw or not, and would exist anyway because they are not born for productivity reasons. "Creation" of humans isn't driven by the amount of work to accomplish.

You are not causing more water to be used by asking a human to work on something.

Same for energy consumption.

This argument doesn't work at all.

What you do for humans to use fewer resources is to work on making us produce less garbage, and produce things using techniques that are less resource-intensive.
