Pretty simple answer actually, they don't. And a lot of the trash they do take with them they illegally dump in Reno. "Leave no Trace" is just a marketing slogan.

1 acre = 43560 square feet, and over the 7 square miles of the event (= 4480 acres) that was the peak measurement? Get real.
"attendees — returned from a week of self-discovery and partying on the 'playa' — have the propensity to dump trash illegally"
I think you need to be fair and compare against the mess left at similar events.
Although it seems obvious Burning Man should provide trash bins - rubbish is generated in large amounts and they should accept that.
Personal anecdote: I attended lightning in a bottle years ago and they had a similar "pack it out" rule. Well that doesn't help when you're not aware of that prior to attending and need to dispose of plates from food you purchased at the event. I guess the expectation is that a day visitor carry around a trash bag full of waste with them all day. It came across as lazy by the event organizers.
Compare this to literally any other event: music festival, political rally, concert, whatever. Your protestations are completely absurd.
Sadly, some marketer is probably reading this and trying to figure out how they can exploit the "cooperative effort and whimsical creativity" of the non-tech-driven IRL networks...
