This works fine when you're sicking enforcement on someone and don't really care, the bigger the blast radius the better, you just want to know who to call.

Where it falls apart is "how do I" type questions because usually the legally factual answer is some huge complex state diagram where three local and four state agencies theoretically have discretionary jurisdiction over a your petty af project or business but the in practice answer is that some agency rubber stamps them all with minimal fuss. You can't make the legally factual answer clear because the degree to which people support the status quo is largely predicated on ignorance, but you also can't come out and say in writing that you have a policy of rubber stamping boring stuff.

Basically the same reasons that all but the most minor and narrowly targeted attempts at permitting reform fail.

The thought is nice but in reality you're basically asking the government to give up power and it takes obscene amounts of political capital to force that to happen in most cases.
