That's not what's happening here. Copyright work remains copyrighted regardless of how you produced it. If you lived in a secluded cave and completely independently wrote Harry Potter and the Sorcerer's Stone (unlikely, I know, but it's hypothetical), you'd be violating J.K. Rowling's copyright by selling it.
Copilot doesn't help people intentionally launder copyrighted code. It may cause people to accidentally use copyrighted code without realizing it. They're still liable.

This is absolutely incorrect. Independent creation is a complete defense to copyright infringement. Funny enough, Learned Hand gives a near identical example to highlight the opposite conclusion ("if by some magic a man who had never known it were to compose anew Keats's Ode on a Grecian Urn, he would be an 'author,' and, if he copyrighted it, others might not copy that poem, though they might of course copy Keats's").
