"Unhook Everything?"
Like, rip apart your laptop and fry the wireless card with a laser?
Latest reports are Intel is going to be integrating Wi-fi chips into upcoming processors, there's no way the NSA
isn't involved in the design of these features, once you have that it's physically impossible to secure your data.
Once a backdoor is installed it can be exploited by anyone with the knowledge and resources to find and crack it, which may not happen immediately, but it's an inevitability that devices in the near future will be impossible to secure (ok, you could use them inside a well constructed faraday cage to prevent wireless communication, that's probably something I should look into if I ever build a house).
And of course thinking that you're not doing anything worth anyone's attention is no security since you absolutely are doing lots of things on a daily basis that are objectionable to many people, it's all a question of who is looking.
