" commodification of information is the only thing that’s made space travel economically feasible. It’s the only commodity whose value exceeds its transportation cost. We’d be exporting biologicals or photonics if it paid. But our trading partners can build the machines and grow the organics much cheaper than we can send them, if they just have the codes and specs. If information were free, the way the radicals want, then there would be nothing to trade, and there goes the only incentive for interstellar ties. "
