Seems to me a better system would be a licensing/deposit system for such events. You can’t pitch a tent unless you’ve paid a deposit that’s refundable a week after the event should your tent not show up in the debris.

A partnership with Decathlon could be made to attach scannable serials to various parts to aid in identification of the debris.

What impact do they expext this to have on lazy rich kids who don’t care about (their parents) money?

Even if the tents get left behind, the tatters will definitely jump on this!

How else will they afford ketamine and to go out drinking in Werburg’s?

As someone who used to volunteer to get into fests for free a bunch back in the day, the amount of shit people leave behind is beyond ridiculous. Still bur ing charcoal grills used to drive me nuts on cleanup. Good way to get free shit though.
