That's not how hypotheticals work. It's just meant to expose the flaw in your logic. In this case you're arguing that demand for a product is not related to supply. That when dvds came out and nobody wanted a vhs player anymore everyone kept making vhs players anyway because 'that's not causal'.
i also explained that free agent's actions can only be said to be caused by their own will. that means that "demand" can never cause "supply" (nor, truly, the other way around), since both those terms actually reflect the willful actions of free agents.
Ok, I get you now. That's just obtuse pedantry. If the demand for animal products goes down, so will supply. This gives an individual the power to lower supply, to choose not to has the same overall effect as killing a few animals. The distinction doesn't matter. Your actions have consequences whether you like it or not. Animal ag cannot survive without money and whenever you buy animal products you are giving it to them.
That's why when nobody wanted vhs anymore they just kept making them at the exact same rate for less and less money. They're still producing billions of vhs players every year and selling them at huge losses because wikipedia said something about supply and demand. You've cracked the code, you're morally in the clear now, you found the magic words that absolve you of all personal responsibility. Hoorayyyyyyyy.
Obtuse pedantry is definitely thought terminating. When you just word spaghetti your way out of any argument or dismiss it uncritically instead of actually engaging with it.
