If sustainable survival is your only goal, go live in a forest. People can survive without factories.
As for your ridiculous hot dog analogy, are you saying as it is now, everyone in the world has as many hotdogs as they want? If not, there is obviously value in making more.
Also, I don’t care how many times you say GDP is not a good metric because it is not fitting your narrative. It is a good upper bound on how much value is produced. You can’t wish it away just because it proves you wrong.
