Even then there will be more flaws. I don't think it is possible to build a 100% secure system in the modern age of 22 abstraction layers between the atom to the data center. Perhaps you do not understand the staggering complexity that lies behind watching a cat video on your iPhone. There are almost uncountable ways to break into the system. This is why there is a bug bounty program from every company - from Stripe (you could argue as a major software company in payment systems) to Microsoft, from Apple to Gitlab, every company has a bug bounty program. Why do you think they give out $1m for a serious bug? If they were not serious about it, that sounds like a big waste of time. This kind of entitlement attitude is usually from people who've never developed a complex piece of software such as an operating system.
