Being somewhat skilled does not make it not hazard. And practices of books are purely predatory.

Books most definitely won’t let you win long term. They only want you as long as you’re losing and can ban you once you win too much. This sounds illegal and isn’t.

Irrelevant. I only bring up the stochastic element because of the implicit argument that people are being victimized by gambling against their will.

Since you would be extremely off-topic if you tried to extend this argument to, e.g., Daniel Negreanu engaging in a game of poker, I wanted to explicitly preclude individuals competently engaging in whatever activity is being deemed 'problematic.'

It was mostly to help the 'other side' stay on topic; otherwise, I could trivially refute their arguments by counterexamples, e.g., Daniel Negreanu.

Do you mean hazard as danger or hazard as luck/random?
