What you describe sounds like half of the goa parties i've ever been to and there's tons of techno and house events that are also not these hyper-commercialized hellscapes. After decades in various sub- and countercultures i honestly don't see much difference between the DIY punk scene and DIY electronic music scenes, while i also do not see much difference between some corporate rave and Vans Warped Tour. It's perfectly normal to have both of the former in the same squat project, and it's perfectly normal for Red Bull to sponsor both of the latter.
