Human laws do not follow laws of nature, or laws of logic. Trying to rationalize why something is or isn't owning or stealing is a misunderstanding.
"It is not missing anywhere, so it isn't stealing" does not apply. What applies is more like "This paper says it is stealing, so it is." The paper says it because a human wrote it there, as a result of whatever complexity going on in their natural neural network.
Please notice I didn't say "right", "wrong", "good", or "bad" anywhere.
