People who say you want regulations: what specific regulations do you want?

And how will they work?

I run quite often into people who say something along the lines of "AI should be regulated", but pretty much nobody ever specifies what they want, and how it's supposed to actually do anything.

So, I'd like some details please:

1. What specific rules do you want? What does the law say? Who does it apply to?
2. How do you detect when the law is broken? What's the enforcement mechanism?
3. What benefit does the law provide? For example, if the law is intended to benefit artists, what happens to eg, make them make more money?
4. What do you think AI companies/users will do in response? Is there anything they could do that would comply with the letter but not the spirit of your law?
