However, when discussing the concept at a high level rather than from the within the frame of how you play, it's a stumbling block for understanding. I can't speak for
@pemerton, but I certainly don't see use of a FATE point to add some fiction to a scene, or leveraging a Flashback in Blades as somehow special or set aside from declaring PC actions in pursuit of player agency. They're all just tools in the toolbox. There's nothing inherently special about declaring actions for your PC that elevates it to a higher tier of relevance. Granted, the focus of most RPGs is to inhabit a character, so it's certainly going to be an almost required tool in play, and often the most common tool. But it's not the only tool and it's commonality doesn't mean other tools shouldn't be considered equally in looking at how a player can make choices and realize those choices about the in-game fiction. Though this is usually via a character, it's not a required component to do this.
