Eventually he can handled it, he can be used to it, he needed to know that in gambling there is always a higher risk that is needed to take, we can never always win in every game that we put our money, there will be times that we will lose the amount we invest sometimes, and maybe sometimes a lose streak will come, but we need to learn and endure the every setbacks in our game, have your emotion be stable as always.
I think that is exactly why these restrictions are in place to see if we gamblers are actually able to handle these losses. Controlling emotions is one of the hardest things ever, especially after a losing streak. For me personally it's very hard to stop after having bad beats. Because my brain keeps trying to find patterns where are none and wants me to keep trying to earn back my losses. I think every gambler will be at the mercy of his emotions a couple of times in his career. We are no robots afterall.
