21M is not a random number...
You should read "Bitcoin: Everything Divided By 21 Million" by Knut Svanholm
This arithmetic only provides the maximum amount of bitcoin that can ever exist, and that number was determined by the parameters set by Nakamoto in the first place?
Here's what Satoshi said about it:
"I wanted to pick something that would make prices similar to existing currencies, but without knowing the future, that’s very hard. I ended up picking something in the middle."
I've seen the Knut short you're talking about, but ultimately, why set the parameters that he originally did?
