Understand they know what NIMBY stands for, but it also applies to people that don't own the land and aren't offering it themselves. As in "Sure encamp on so-and-so's land, its not hurting anyone" while you don't have a yard, or give a homeless person room in a spare bedroom. Everyones free with other peoples backyard, while not in theirs. I don't want them in my backyard, and neither would they if they have ever had to put up with it.
