This would be completely logical if MP3s from Taylor Swift were found organically in nature everywhere we looked. Unfortunately (or fortunately), this isn't the case, so there are no "natural rights" to be asserted here, as is the case with things like food, water, and shelter.
There is a natural right to freely copy information. Our civilization is based on our ability to tell young people the stories we heard from our elders. And we are part of nature.
So, in your opinion, someone taking part in commerce is completely justified in simply copying software without paying a dime to the author, and using that software to then, in turn, make money ? Who gets to decide when one person's rights trump another person's rights ?
