But they are not changing position nor velocities with respect to each other while rotating, they are changing positions and velocities against other frames of references.

They are though. Structures are not rigid, but more elastic. They only appear rigid and monolithic from a macroscopic perspective. One atom moves relative to another , and then exerts electromagnetic force on another which then moves a bit itself, and when all are seen together they appear to be a single unit that is spinning, but that is an illusion.
