But more importantly, putting everything up to a vote will just lead to oppression by the most vocal people with too much time on their hands. The bar for allowing something shouldn't be "do the majority of people that are involved in this sort of thing want this"? It should be "do enough people benefit from this such that its a viable business"? Then you can make sure the business is following reasonable laws. For instance if the drivers are speeding or breaking noise ordinance, then they should be forced to obey the law.
