If $D$ is a stable monoidal $\infty$-category then the theory of Smith (co)idealsideals tells you that if you have a monoidal functor $F: \mathbb{Z}_{\leq 0} \to D$ then the fibercofiber of the map $F(-1\to 0)$ is a monoid and every monoid arises this way.
If you take opposites this should tell you that a well pointed endofunctor must be at least as complicated as a monoidcomonad.
