In order for there to be no experience of a force acting upon a body in free fall in a gravitational field all particles in the falling mass must be acted upon simultaneously by gravity.

It's a common misconception to think that all bodies fall at the same rate in a curved spacetime. That's only true for point particles. When there is a body present having a finite extent then there are different forces acting on different parts of the body meaning that the acceleration of the body depends on contributions from all those forces.
Back to front reasoning. "In order for there to be no experience of a force...." is a condition which requires a nonuniform gravitational field. The concept of spaghettification under extreme gravitational attraction is all about significant forces acting throughout a finite body. You can't "reduce the complexity" by ignoring the laws of physics or assuming an arbitrary condition to hold true under all fields: you'll just confuse yourself.
