You should not expect to get something for free if its on private land
If you're living out of your truck and dirtbagging it you are choosing to do so and the land owners owe you nothing. They are climbers too I guess and would, could understand that life style and might have a special fee for Dirtbagging climbers or a yearly parking fee. But to go onto someones land and not "donate" for the cause is horrible.

It seems to me that some of this population has a sense of entitlement already and is making hard for this land owner to keep up the goodwill.
And it seems that climbers aren't able to police themselves and have someone stand up and say "hey slap a fiver into the can and stop messing up this piece of land" aka pick up your tape , trash dogs shit etc.

Please put as much energy as you have by coming at me while you're out at the crag to keep people in line to keep this area open and the landowners happy
