To be fair, wouldnt you set ground rules for your guests if you threw a house party? If those guests dont abide by your rules, you're just going to embrace them to keep doing it?

Ragging on them simply because they want to put ground rules down, so everyone can have fun, is pretty immature. Yes concerts need rules. The venue can be held liable for certain things drunk/high dumbasses are going to do. You need to be specific about what rules are so dictatorish or you just sound like a 15 year old pissed off with their parents.
