Feel free to post a quote where anyone in this thread said you can land "anywhere." No one is talking about "anywhere."
I don't mean to be rude but you are being very slippery. "Anywhere" is not the same as "everywhere."
I'm still waiting to hear how in "all fifty states" you "must" have received the owner's prior permission to land.
Must I call the BLM in advance every time I want to land on their land in Alaska? If I land in a farmer's field in Montana must I have called him and asked permission in advance? If I don't, what is his redress? How about in Nevada? Arizona?
How about
Colorado David? If you are sitting on your porch in rural Wheatfield county and see me land out by the creek in the distance, what law have I broken and what can you as the landowner do about it?
And no we aren't talking about zoning. We all know about zoning.
I can't believe that as a lifelong bureaucrat it is I who have to lecture some of you about the concept that if something isn't expressly prohibited by law than it is permitted
And David while wisdom, courtesy and common sense have a role in this discussion I am talking about courtrooms and summons, since some are ready to throw the book at the helicopter pilot.
