With all due respect, this is a single player game. Players play the game how they want to, at the difficulty they want to. I suppose you could add a warning “May break the game!” to some options.
Basically ou are right of course. Every player should be able to play a single player game the way he enjoys most. The tricky part comes into play when we have to drop other features just to implement this one. We always have to prioritize very sharply to not overburden ourselves and lose focus of what we are really trying to achieve with the game.
Cheers!
