That was a very interesting read,
It would in theory make the computer very secure but at the cost of functionality, which can granted be increased only by opening a series of ports for the traffic to come in and out. each port you open someone can come through the port unless you block that persons IP,
the advantage of having a firewall is that it will check the packets and block the ones you don't want as defined by a series of rules and log the packet in question.
It is not recommending that you do anything improper with system controls.
You are right it would improve security, but only to a point. essentially blocking ports so as they are not connected to the internet, reduces traffic but hackers can still get through the open ports.
I don't think it is as tight as third party firewalls as they have the ability to log access block inbound and outbound access.
