And there's the rub. Even if we could make 500lb all-tenderloin cattle you wouldn't see people buying hundreds of pounds of beef tenderloin for themselves every day. Billionaries like Bill Gates can already afford millions of pounds of tenderloin yet you don't see him eating that.
Basic income might cause the price of tenderloin to go up a little bit but so what? It's not going to do anything to the price of corn or rice or wheat. Maybe the price of an apartment in Manhattan will go up a little bit (I doubt it) but not a house in rural Wisconsin.
