This is by definition the problem with all security. Every type of
security, from bank vaults, hotel rooms, to vpns sufferer from people who
don't protect the master keys.

*Any* security infrastructure is a central point of compromise. That's the
nature of security. You are left with either an unmanageable mess or
forced to use or create some sort of infrastructure to manage it.

ANY security system is vulnerable to bad actors that can gain access to
sensitive data. With a CA on openvpn, merely regenerate your master key
and push a new cert. When users can't connect, they have to re-validate
and obtain a new key.
