> Why then, would gravity not be a force?

But you did not explain force you just redefined it to suit your argument. In the Newtonian regime force is defined as action at a distance between two masses. Your notion of field does not exist in the Newtonian regime.

Einstein did not believe that action at a distance is possible so he tried to explain gravity without action at a distance, ie, without force.

Gravity cannot be a force and not a force at the same time. It's either a force or not a force.
