I agree that there is usually a "good reason" behind many regulations. The issue is that the law applies with unbending force. Regulations would be both less necessary and less onerous if we could conceive of a more flexible, fluid legal system. It's not necessarily a valid implicit assumption that the regulations that apply to professional hoteliers should be applicable to individuals taking on short-term boarders.

Justice is very slow and very expensive under our current model. I understand that there are a lot of complex mostly-good historical reasons why things became that way. But we need more legal fluidity and better legal accessibility.
