Well, I just popped in "Write a new Federal law banning the collection of melted snow by individuals or small-business proprietorships for the purpose of protecting endangered plant species. Include a loophole that excludes minority-owned businesses or people who contribute a sufficient amount of money to carbon sequestration technologies or senators or representatives who voted in favor of strongly pro-union causes." and I won't burden HN with the results but it definitely has the shape of a fully-fledged bill for Congress to pass.

One problem ChatGPT would have in its current form is it would need auxiliary assistance to craft a larger-sized bill, as bills easily exceed its current window size. But that's a solvable problem too.
