Ok, first, ,
https://en.wikipedia.org/wiki/Dodge_v._Ford_Motor_Co. yes, "the Michigan Supreme Court held that Henry Ford had to operate the Ford Motor Company in the interests of its shareholders, rather than in a manner for the benefit of his employees or customers."
RPL; I'm gonna again advise you to ignore him. He will think what he will think. You won't change that. Nothing good comes of this.
Now can we please move on?
Agree, may not be as "efficient" by some measures. Building upwards requires artificial light, so building shadow is relevant but mitigable point, potentially. You mentioned "On the other hand, using your house to inefficiently grow food is a better usage of that solar energy than you were likely using it for already, so why not supplement the food supply from farms with a smaller food supply from houses?" Agree, especially given that we are not good enough at storing electric power right now, and we need much better batteries. If power production capabilities keep increasing but storage (battery) doesn't keep improving as much, why not make that energy used as a grow light/heater/plant nutrient pump? (If you can't efficiently store it).
Suboptimal uses may have their place. Suboptimal capacity production + optimal capacity production = greater total output than just "optimal capacity production" IF the "suboptimal capacity production" can't be better used overall. In essence a home that produces some food compared to a home that produces no food produces more food. May not produce as much food as a farm field but you can live in the house, not the field.
Simply, Let's say the fields produce ... "10" (a nice round number).
Let's say the house produces ... 2 This is indisputably less than 10.
10 + 2 = 12.
12> 10 (production with house and field verses field alone. Would be "11" if house produced "1" instead of "2").
Home additionally provides shelter, while the field does not. Home provides other "value" or worth aside from food.
Everything demands energy. Trade off between plants and solar panels depends upon placement. Your point may be valid, in re "larger scale ventures" producing more food and home specialization in energy production resulting in more overall. (We don't have the math, which would depend upon future advancements). Specialization may produce greater overall yields. This depends upon if combinations of things can produce more desirable outcomes in combination (see also
https://www.energy.gov/eere/solar/agrivoltaics-solar-and-agriculture-co-location), rather than strict specialization.
With future advances, might turn out combining solar panels with crops results in more plants and power. Unclear.
Risk, rather than straight production, factors in as well. Drought impacts crops, but not solar panels?
Consider combining both insurance: lost the crop, kept the solar power production.
But having plants and fresh produce around is a quality of life improvement over living inside a bubble of solar panels.
Agree entirely, qualitative improvement matters, even if difficult to quantify. It's unclear even today if presence of solar panels increase or decrease house value. I would personally consider paying more, but some places tried to ban them for "appearance" reasons. That's subjective, oddly. Logically a house without a power bill (due to solar/wind) would be cheaper to maintain, and more desirable, but ... some people hate how it looks?
You will have people saying,
A.) "This house that costs $100,000 (I know, but nice round number) and that's better than that $110,000 house across the street with those weird solar panels on it."
B.) That $100,000 house across the street has no solar panels and it's better to pay $110,000, because that way there's no electric bill. That other house's $100/month electric bill will add up to $10,000 in 100 months (about 8 years and 4 months, assuming electricity bills don't increase). So after 100 months the solar panels pay for themselves. That other house across the street without the solar panels will be worse long term.
This is an investment choice people seem to make and there's not a ton to be done about it. You could logically apply the same argument to food growing infrastructure as a feature, and again, get the same two viewpoints. Some would still hate it.
