This is the case with most access prevention devices, particularly as
implemented in softwarer.  Hardware may pose other problems.

The point is that it's almost always possible to replicate the encrypted
data directly.  Note, however, that this generally doesn't involve
circumvention of the access prevention system itself.  Thus, it's not
copying, per se, but *access*, which is prohibited by such devices.
This is a point raised in the 2600 case, Kaplan's to date been unmoved
