Uh oh, you just deflated the Libertarian prime directive that all inanimate objects are created equal.
They won't like that and go on a new jag of tantrums.
Granted.
The right of a farmer to grow and sell crops isn't the RKBA.
The right of a businessman to hire and fire is not the RKBA.
In fact, nothing else is the RKBA.
So what?
Well, I'll concede that the RKBA is the guarantor of all other rights; that doesn't negate the value of other rights, IMHO.
