Yep. But if it still commands economic value for its creator and you cut that off, then it is reducing that incentive to create and cultivate in the first place.
You are assuming that incentive to create keeps increasing with more monetary reward. Incentive doesn't start out at zero without rewards (see history before copyright) and is never infinite (what good is infinite money if you never get to use it).
Brand is valuable for consumers and protecting that brand only makes sense if you continue to have ownership and control over it.
For a non infinite money glitch version of this, see “Calvin and Hobbes”. Would the world be better if those characters could be printed on random merchandise?
