That's not how Bitcoin works at all. No amount of the supply (or hashpower) can let you make arbitrary decisions.
Having 50+% of the hashpower could let you double spend by mining on two forks in parallel, but it will never let you change the rules of the protocol, since these are defined on clients run by many people.
In fact that is what happened in the article. Someone realized there was a problem, got everyone to change their clients, and it changed. The first person to notice the bug did not need to hold any Bitcoin at all to make this change.
Right but some number of humans can collectively decided to change literally anything about Bitcoin. It isn't some fundamental constant of nature. The question really is who are the humans that could actually decide this, what are their incentives, what would make them decide to change it? If only you and I are running the original Bitcoin code then it isn't really Bitcoin. "Real" Bitcoin is a function of human decisions and has fundamentally very little to do with the code. Purchasing Bitcoin is simply a decision to trust this group of humans.
This group of humans is anyone else who decides to run the same version of Bitcoin as you
Yes, but who actually decides? I doubt it is as egalitarian as it seems. Perhaps to put it in monetary terms, how much money would be required to incentivize this group to double the number of Bitcoin? Would $999T be sufficient?
