Well, modification of certain software systems could be easily regulated. Even now you can't just modify all the mechanical parts of your car. For example, if you remove or bypass your catalytic converter, you can be fined $2,500-200,000 and charged with a felony. There's also a provision for any citizen to sue you into compliance if they know you've done it.

Or any of the million other felonies you might be unknowingly committing due to the expansion of federal regulations.
