After rereading the article, I now understand that you were referring to this quote in the article : "The circulation number is not enough".
You are right, the fact that it's divisible render this point moot. I thought you were saying that dividing coins somehow decreased scarcity (Yes, I've seen many people argue that, believe it or not).
Original comment below :
I find it really mind boggling that some people don't understand that dividing a pizza into 100M pieces does not give you more pizza.
There is a purpose, but it's not HFT... It's orbital mechanics.
You can't have efficient coverage of the whole planet without launching all of your satellites at fairly high inclination (>45°). There will be more satellites per area near the poles and so that's why Starlink will be available at very high (and very low) latitude before it's available at the equator.
I'm not saying the price can't increase, I'm saying that dividing coins does not reduce scarcity.
Edit: Updated my original comment, turns out I'm the one who misunderstood your point. We actually agree.
