Not really, you can just add more and more control points to a Bézier and it will be possible to describe a curve to a greater accuracy.

However, in reality when using Bézier curves you want to really want to use the minimum number of control point neccesery to ensure a nice smooth curve.

The more control points you add to your curve the more computationally expensive it becomes, though.

This is just the law of spline demand.

Excellently integrated pun!

I mean vice versa. Can the physical thing do any CAD Bezier?

A Bézier curve can have a cusp, which you can’t do with a physical spine.
