I made this same argument many moons ago. Basically, why not use it for craps, roulette, baccarat, everything?

If win goals and stop losses work in some material way, they should be applicable to everything. Obviously. And if they worked in some material way, people would have been using them for hundreds of years, and we wouldn't have any casinos, unless you want to argue that our generation suddenly jumped 100 IQ points over past generations.
