From https://en.wikipedia.org/wiki/Nomic
"While the victory condition in Suber's initial ruleset is the accumulation of 100 points by the roll of dice, he once said that "this rule is deliberately boring so that players will quickly amend it to please themselves".[1] Players can change the rules to such a degree that points can become irrelevant in favor of a true currency, or make victory an unimportant concern. Any rule in the game, including the rules specifying the criteria for winning and even the rule that rules must be obeyed, can be changed. Any loophole in the ruleset, however, may allow the first player to discover it the chance to pull a "scam" and modify the rules to win the game. Complicating this process is the fact that Suber's initial ruleset allows for the appointment of judges to preside over issues of rule interpretation."
So not only would 'give me infinity points' presumably not win a unanimous vote; but the whole idea of "getting points" is designed to be gotten rid of in favour of something more interesting.
If you proposed a rule change that gave you infinite points, the other players would vote it down, because it's easy to see that that rule rewards you at their expense.
You can land self serving rules though, you've just got to be sneakier, and slip them in as loopholes or the like.
