Makes sense. That said, fidgeting and moving around is spontaneous when on the floor, you don’t have to be reminded to do it. Also, no chair is cheaper than an expensive chair.

Indeed, it's actually what prompted me to go look over the document.
I remember, as a kid, when out and about and before getting into the habit of sitting in a chair all day every day, I would sit on the floor or on random objects, like stones or tree trunks in the countryside. I wouldn't be able to sit still for long periods of time and would need to at least change positions.
Whereas now, in my "ergonomic chair", I can sit for more than one hour at a time with minimal, if any, changes in position. Ditto for my couch (which wasn't marketed as "ergonomic" in any way).
That being said, I've tried using a computer in other positions, like putting the laptop on a coffee table and squatting or sitting on the floor in front of it, or having it rest on my thies while squatting. It gets tiring very quickly, especially in the shoulders and neck area.
So, in my case, what seems to work best is to get up regularly and walk around the room for a bit.
