1) Because these methods encourage the growth of big business Hunting ranches and they take over hunting's public personna. High Fence, pen raised hunting operations are shaping the the public's opinion of the modern hunter. I personally DON'T don't want to be associated with certain hunting practices that give hunting a black eye.
2) Big Business is buying/leasing up the land driving UP the cost of leases

3) Because of 1&2 hunting is now a bait and sit sport where hunters are confined to so many sq ft and no free ranging hunting is allowed
