All of these except for the last require medical staff, not security. In my experience, the medical staff at festivals of all sizes are amazing people. I don't see how an illegal rave could ever have medical staff though so it's a personal risk that people can choose to take. As for people not understanding boundaries, small groups of adults, up to a couple of hundred, are generally self policing. I've witnessed a couple of guys being forceably ejected from gatherings, but over the hundred or so I've probably attended in my life (raves I mean) I've only seen this being required a couple of times.
