Sorry, but this won't fly in court. Any interaction with computer is "using the hardware".
Owning the keyboard does not allow you do go hack anybody because "they are unable to dictate which buttons that you own you are allowed to push and when".
Hardware is a tool. Its ownership does not give you blanket permission on use it to any imaginable purpose. Same as owning the knife does not automatically allow you to stab people because "its my knife".
We're all just bickering about a trivial video game, no formal legal body is ever going to touch any of this rubbish with someone elses ten foot stick.
