You're just reiterating the author's point. Not every piece of software written faces dire security ramifications like leaking user identity. Not all software is loading or touching user data at all. Not all software is running in trusted environments. The premise is that Rust may be a good fit if security is a key concern, and even then I would argue it's likely possible to partition the domain into security-sensitive and security-insensitive domains. Cherry picking problem spaces where security matters and making claims about Rust goes against the spirit of the argument.
