I only see people with no self-control and incapable of accepting a wrong roll, none of you would survive a tabletop session.
1/ At least for me, self control has nothing to do with this. The problem arises when you like both equally :
- playing a game, living with the consequences of your actions ;
- getting the best outcome of a situation.
As you like both equally, you can't decide what you want more during each dice roll. So you want an option in game to remove the choice, so you can enjoy playing the game "with consequences" fully.
2/ People like this would have no problem "surviving" during a tabletop session, as that would, in fact, resolve their problem. That's exactly what they ask. people who want to keep the ability to savescum and who want to use it every time are probably the ones who would have a hard time during a tabletop session.
