I've been to several big festivals and they were run just fine, I didn't see anything I hadn't also seen on busy streets in SF (less actually). People without the proper experience hosting a festival for tens of thousands of people does end in failure, but plenty of festivals are actually prepared and organized for what goes on. If people taking off their clothes and doing drugs while dancing and experiencing music disturbs you, a music festival isn't for you, but it's also one of the oldest organized human activities.
