Yeah, I read that article about the Harris amendment and it was a cute legal theory, but I don't really buy it. It certainly wasn't validated by any court -- nobody would even put their name on it! It certainly isn't proof that an amendment couldn't be crafted that would prevent legalization.
My understanding is that literally everything the city does requires at least some nominal amount of staff time and funding, so Congress has considerable power through the appropriations process. But IANAL. It would certainly be an interesting court case.
