You are completely wrong...

1) AIM, ICQ both have been vulnerable to buffer over flow attacks which
allow "hackers" to take over a work station

2) P2P software could allow for potential network take over

3) E-Mail viruses, trojans etc.. could lead to network take over

4) IRC could also lead to network take over..

There are many many more examples, you are never completely save, never
ever if your computer is connected to the internet you are not save... NAT
is not the be all end all firewall..
