If you never want Touch ID to work, you can just replace the home button in the phone. It's a security feature from Apple--a new home button will never work with Touch ID again.

It's not too difficult to swap a home button yourself with the right tools, or most stores will do it for ~$49 to $59 (depending on your iPhone model.)

If you have a store do it, definitely ask for your original home button back in case you change your mind later or sell your phone.

Just don't setup Touch ID?

Obviously, but if you're as security-minded as this article author is, I'd trust a hardware solution over a software solution. It's the difference between turning off your camera and actually unplugging your camera (for instance.)

Except, it's really not. If you've never set up Touch ID on the device, then there's no fingerprint for it to even compare to; it'd be impossible for it to authenticate.
