Somewhat, yeah, that's the nature of barter. Unless one side has the other by the balls, the value is determined by both parties.

But when you're dealing with intangible things like ideas, and that which can be replicated at almost no cost, with no actual provable loss to the creator.. It gets a lot more murky. I mean, if someone took a loaf of bread that someone was selling. The baker can't sell that stolen loaf of bread, there's a tangible loss there. If someone copies a concept, maybe tweaks a bit here and there to improve it, there's no loss. That idea can still be sold.
