I doubt it will get any better, you can't do anything nowadays without there being a regulation or rule to follow about it - and the worst thing is they never tell anyone about it your just expected to know. The bouncy castle is a classic example though - there is nothing wrong with them as long as they well secured with stout pegs all around - and not used when it is windy - all common sense really. Instead of trying to ban something they would have been far betting requiring a pre-use safety check by an official that was charged for.
