Then why on earth are you playing a game which is purely about hypotheticals to begin with? It's like if someone were to sit down to play Monopoly but refuse to hand over rent because "I believe that having a dwelling should be free". Ok, good for you, but then it's really foolish to play the game to begin with.
The point of the game is to illustrate this behavior. That is why they use a real-world example, to produce different results when different people are asked the same question. It's not a math problem.
