On the one hand, it shows how antagonistic DMing is silly. The DM can just make stuff up, and the reason we’re all playing is to have a good time. If you want a competitive game that’s (at least ostensibly) balanced, you can play one of those instead, like a board game or a war game.
On the other hand… modern D&D is built around ostensibly balanced set piece encounters, usually combat, usually intended to tax but not kill the characters. So the fact that it absolutely sucks at being a balanced game is an absolute nightmare to DM (assuming you want the game to be fair & fun).
