Yes, exactly. Consistency is important, because it builds and reinforces trust. The GM just saying "nah" is the other side of the player showing up with a homebrew bullshit build.

I get a lot of pushback from the Pathfinder 2e subreddit for promoting the idea that the system is really great for character-driven, fiction-first tables, because everyone just looks at the number of rules and goes "it's so obviously a gameist system, why would you ever try to run it as anything else?", and the answer is it's a fantastic physics system. The rules provide clarity and consistency where it's really useful or important, and are easily ignorable where it doesn't matter.
