We live in an economy of mass computing, because it is way, way cheaper to perform a calculation on a mainframe than a microcomputer on your desk.
In areas where there really is mass computing (i.e., heavy number crunching), this statement is actually true.
Most of the arguments against 3D printers are essentially the same as though used against early microcomputers. Yes, those early microcomputers were never going to change the world, but their descendants sure have.
Microcomputers slaughtered mainframes in the marketplace because there was not widespread network for information transfer that mainframes could benefit from. Now we have this network and people are moving towards centralized computing facilities (the "cloud"). For physical goods, such distribution networks have been in place even longer so there's no economic benefit from switching to hyperlocal manufacturing.
