But then I can turn internet on without needing the usb stick. I would simply run "iptables -I OUTPUT DROP" myself.

I'm not sure I get what you propose. I have root access to my computer. So if I can set up iptables to drop packets, then I can also turn it off pretty easily. I have tried similar software solutions before. They work as long as you don't break them. But if you break them even once they become useless. The idea is to keep the USB key away from my office. So when I need internet I would have to fetch it, which would take me about 10 minutes. This should give me enough time to not act impulsively.
