Integer factorization for codebreaking is a military or criminal application, not a commercial one. Someone will make money doing it, but it won't be contributing to society in the way we normally mean when talking about commerce. It would be like saying nukes have commercial applications.
"Quantum simulation" is too vague to speak to applicability in any domain. There is no proven or empirically demonstrated exponential speedup on any simulation problem with known commercial applications.
