By blocking HTTPS wholesale. You appear to be assuming that isn't a valid network configuration. Believe it or not many large corporate networks do so, and use web proxies to allow connection to websites (including HTTPS sites, some with MitM corporate certs, some not) and those proxies whitelist access based upon the domain you try to connect to, and route that traffic for you.
