Data cannot 'erase itself'; when people say this they're referring to software which erases data. But software itself is nothing but a special type of data which is loaded and executed by a piece of hardware. So on a more fundamental level it's always the hardware that erases data. Indeed, with the right hardware (magnets or EMP bombs or whatever), you can erase data without using software at all, so it's incorrect to say that only software can erase data.
This is even more tangentially related to my game than the original entry was tangentially related to DRM.
