How can you steal pixels?

Or rather, what does “ownership” mean? What does it mean to own light waves? What does it mean to own sound waves? Etc

You can’t steal pixels or frequencies. But you can use someone’s image or their voice to sell your product without their permission.

You can get all existential about it if you want - I just know that if someone used my face or my voice to shill for a product without my permission i’d be pissed. I’m pretty sure you would be too.
