Interesting thoughts here-on both sides of the question.

I must say that I really like this little analogy:
To me, bragging about how good the fishing is on a piece of water you paid to get into is sort of like bragging about your prowess with women when you hired a lady of negotiable affection for the evening. If you can succeed where anyone else also has a shot at it, now that is more my idea of skill
I also have to say that if I was a high-roller I know that I would probably be more open to the idea; however, given my current economic situation I don't consider this worth my money and probably never will. I say this because I wouldn't have a problem paying $10 per day to fish a quality trout fishery if there was one to be found in close proximity to me. For me it honestly isn't a question of ethics or values but one of COST versus VALUE.
