> Exclusive book deals tend to have defined timespans
Good. We have "enumerate[d] [at least one] inaliable basic [freedom] that peopke should be able to deal in".
Of course, we can quibble over the permissible duration of such timespans, but I think the point has been made clear.
Just to be clear: you're asserting that "there are some inalienable rights" can be debunked by the existance of one that is not inalienable?
That's not how this works.
