The model assumes gradually diminishing returns to spending within the next year, but the intuitions behind your third voice think that much higher spending would involve marginal returns that are a lot smaller OR ~zero OR negative?
Huh, now that you mention it, I think the third voice thinks that much higher spending would be negative, not just a lot smaller or zero. So maybe that’s what’s going on: The third voice intuits that there are backfire risks along the lines of “EA gets a reputation for being ridiculously profligate” that the model doesn’t model?
Maybe another thing that’s going on is that maybe we literally are funding all the opportunities that seem all-things-net-positive to us. The model assumes an infinite supply of opportunities, of diminishing quality, but in fact maybe there are literally only finitely many and we’ve exhausted them all.

A counter to that second thing is: Well we can always just give to GiveDirectly or something like that.
