The speed of light is the speed limit for objects having mass moving thru space. It does not limit how fast space itself can expand. So objects in an inflating region of space have no choice but to go along for the ride. If they don't, if they try to drag their feet, they will then be moving faster than the speed of light with respect to the inflating space they're embedded in, and that's not allowed.

Atoms “moving through space” implies an absolute frame of reference, which I think is disallowed. Relative to one atom, another atom moved away trillions of miles, let’s say ~1 light year (6 trillion miles), not in 1 year, but in 10^-32 s. I don’t know how else that could appear to the other atom than as having superluminal speed.
