If it is not tucked, you can't untuck and vice versa. Tucking and untucking is a side-effect of the vertical roll of the dantien (ie one of the two key movement planes of the dantien, along with the horizontal).

The coccyx is the tailbone-- it is not the pelvis, it is not the hips, and it is not the sacrum.

None and all. The question is based upon a faulty premise. If the body is moving, the coccyx is moving - it is not held in a static position. "When one part moves, all parts move."
I'd disagree - to a degree.
A beginner has to start somewhere, and in the Chen Taiji I have learned, that somewhere is ZZ. Start from stillness, then proceed to movement.
