Certainly there's no technical problems with it, but there's clearly a practical problem with it. Laws are rarely simply removed. Clauses may be struck, future laws may rewrite (and inevitably expand!) past laws, but it's very, very rare for something to simply be unambiguously removed. When's the last time the government simply eliminated an agency, for instance? It's not zero, but it's one of those cases where simply the fact that one must hunt for an exception to argue against the point is something I'd cite as evidence for my point.
