It's worth noting that LNT is also a requirement of the space (a BLM wilderness area) and their permit. I've been involved in organising rocket launches at the same site (well slightly north) and we are required to do the same thing - the BLM inspects our site (and Burning Man's) afterwards, it's a condition of our ongoing permit.
When I first started going out there (before Burning Man) there was a century's worth of junk out there, we spent a lot of time helping the BLM clean it up - well most of it, there are millenia old archeology sites there and 200 year old covered wagon debris which are protected, but the tires, car wrecks, all sorts of junk had to go - we appreciate people putting in the work to keep it clean
