who the heck is gonna regulate commodities, etc out in space?
Same people who do it on Earth. Just because you choose space as the place to do something shitty doesn't mean you won't have to answer for it here.
But, you're right. Since the internet is used to facilitate some of those things, might as well throw up your hands and spend every waking hour basked in the glow of a screen until you die.
Don't like the terms? Don't license it. I'd prefer to see the whole permission culture shit go away anyway. But unless you're going to argue that they shouldn't have any say on whether their arms are presented in a game at all, it's a little absurd to argue that they shouldn't get to negotiate how the arms are used in the game as part of the licensing deal.
Never say you know a man until you have divided an inheritance with him.
