Actually this is very much how people think for code.

Consider the following consequence. Say I work for a company. Every time I generate some code with Claude, I keep a copy of said code. Once the full code is tested and released, I throw away any code that was not working well. Now I leave the company and approach their competitor. I provide all of the working code generated by Claude to the competitor. Per the new ruling, this should be perfectly legal, as this generated code is not copyrightable and thus doesn't belong to anyone.
