For many of these friction fit adjustable height chair and stool pedestals, I’d skip the rubber mallet and definitely skip hammers.
The easiest method is to place the flattest end between your feet and apply steady pulling pressure while gently rocking back and forth.

I tried that first, to absolutely no avail. The darned thing isn’t going anywhere.

Hmm I see. What I may have left out is that, since the goal is to use the prying leverage offered by the length of the shaft, the end you aim to free should remain as flat as possible while you apply that prying force.
One of the easiest ways to ensure this is to use body weight to keep that end flat on the ground. If that’s not possible or too difficult, you can alternate pressing down with one foot then the other, then rotate the shaft 45 degrees, repeating until it lets go.
This method uses the fact that a cylindrical friction fit tends to have one radial axis applying the most cumulative friction on the shaft. The prying force shifts the oppositional maximal friction points to a different axis, and the steady pulling force during that shift allows the collar to be incrementally extracted from the cylinder.
The key thing to bear in mind, however, is that these increments can be tiny, meaning you won’t get much if any perceptible feedback indicating progress as you proceed with the pry-pry-rotate-pry-pry-rotate cycles. But if you drew a line with a greasemarker on the outside edge of the exposed length beneath the collar, you will likely see the collar’s incremental extraction progress.
