Because it is so limiting that it will become repetitive. With Lobov-Knight and Beltran-Lopez before that, I've already seen all that bare knuckle can offer. It's just two guys headhunting. I don't see room for evolution. BKFC 200 (assuming it survives that long) will look no different than the last event. And by then, we will be so desensitized that even the gruesome spectacle of scarred up faces will elicit a "meh" from most fans. I want to like BKFC but I feel I'll eventually be bored by the same old, same old.
