It's a fantasy. We've all played enough games to know that any system that allows players to get ahead by making better decisions than other players will devolve into a degenerate state without constant rules changes. And as long as there exists players who are better at leveraging the rules than the people making the rules, the rule changes will be very ineffectively at limiting their ability to continue getting ahead in the game.
In the history of MTG, the competitive game with the most complicated rules (over 200 pages of legalese, even AI sucks at it) there exists three kinds of players:
People who play to have fun.
People who play to prove they're smarter than their opponent.
People who play to prove they're smarter than the people making the game.
(Okay there's a 4th secret kind of player, Commander players, who play to prove they're morally superior to other people at the table while being smug as fuck, but let's not talk about those people. Actually, those people are kinda like crypto nerds, so maybe we should.)
