Negative. Go take headshots at a photo place. You don't have the right to make copies of your own headshot without permission from that photo place. Your own headshot would literally be you as the primary subject. Yet you still don't have rights to it unless your contract with that photographer says otherwise.

In your own link the first answers even states it...
The photographer is normally the sole owner of the copyright in the photograph.
Subjects having any rights to the photo is rare, short of other laws being broken.
Edit: Hell my own kids school pictures. I have to purchase a digital copy of the photo to get a release from the company to make my own prints. EVEN ON MY OWN PRINTER.
