Gravity is not an "emergent property of the geometry of spacetime" as you say.

Gravity can be modeled as such. Just because you can model "spacetime" this way doesn't mean you understand gravity.

We don't understand what gravity is. We just have a good way of describing mathematically how it works on large scales.

We could model electromagnetism in a similar way. In fact, that's pretty much what quantum electrodynamics is. You can model electromagnetism as a phenomenon of the "quantum field," which is the manifold physists use for their mathematical description of electromagnetism on quantum scales.

"Spacetime" and the "quantum field" are simply abstract concepts that are useful for making the math work. We shouldn't think of them as concrete objective things that exist, because we don't know that.
