You do bring up an interesting point. However, the wage in question is value tied to the work that you've done. It is inherently a payment for a service not goods. You cannot really "steal/duplicate/pirate" a service. How would it work anyway?
And, the copyright owner didn't own any "wages"/profit just because you have copyrighted material. This is problematic because goods can be copied hence the need for copyright and patent law. You could get secondhand copyrighted goods and you don't owe the copyright owner anything.
