It depends on what they mean by agency. There are two different primary definitions for agency. 1) player control over the fiction(authoring, etc.), 2) the ability to choose what your character says and does and have it mean something.Suppose that someone GMs exclusively adventure paths. And insisted to you that players in their game have as much agency in your living world sandbox, and that they prioritised player agency to the same degree as them.
Would that prompt you to retract your remark that "If I didn't think agency was important I'd just run a linear campaign or use a module" - a remark which*clearly* implies that an AP game does not prioritise agency?
Or would you form the view that the AP-er is mistaken?
Also: why are your criteria "natural" but mine "artificial"? Are the criteria by which you judge that your RPGing involves more agency than AP play artificial ones?
You favor the first kind of agency. I favor the second kind of agency. Neither one is better or worse than the other, just different.
If the hypothetical DM you propose above were to claim to have as much of your kind of agency, I'd say he was wrong. However, if he was talking about my kind of agency, and his players had meaningful control over what their character says and does, I'd be fine with his claim to have as much agency as my game.
In both his game and mine, the players have full agency to declare what their character says and does. The DM above has just gotten his players to agree to linear play, so their agency goes fully in that direction. My players can go in any direction, but that doesn't increase their ability to affect the game through their actions and direct what their PCs say.
