Part of the problem with your argument is that in order for e,g, a web
server to be reached, port 80 (and maybe port 443) have to be allowed
through the firewall. That fact alone means that the webservers have
to be patched, because as long as the firewall is allowing legitimate
traffic through, it could also be allowing malicious traffic
through...
