hence why putting chip production in everyone's hands will flip the game.
No. Then those with more money will print faster than others. You end up with the same situation. If a 3d printer takes 1 hour to make a chip and the printer is $1, someone with $100 can buy 100. Someone with $1m can buy 1m of them and hire others to help run them. In that case, the guy with $100 still just has 100/1,000,100 of the hash rate and will get almost nothing. Not to mention the guy with more money would go straight to the manufacturer of the 3d printers and offer a premium to obtain all of them that are created, as opposed to marketing it to the masses.
