I like the guy's spunk, and I agree that he has a choice. He has no obligation to participate in any of it, provided he does no harm to others.
I'd have to see how far the anchor encroaches, and how big his property is to decide if he's being a pissant, or has a square-up beef.
However, I can't really get behind cutting/destroying the anchor. Not because he shouldn't damage power company property, but because he wantonly endangers/punishes those who are not part of his personal conflict.
That right there is where he stopped holding the moral high ground, in my book.
