Bitcoin is not a free for all. It is a system of rules that are purpose born. When somebody finds a way to exploit a loophole in those rules in a manner that does not respect the purpose of Bitcoin, that loophole must be closed to ensure that the system can still serve it's purpose. When a dude found a vulnerability that enabled him to mint 184 million Bitcoin, the developers fixed it, and nobody was screaming "muh free market!" over them fixing the code.
