I don't think that it is GPL compatible.

It is basically impossible to do what you want. When you sell a
person a physical thing, they automatically gain certain rights. They
are free to do modify the thing however they want and then resell it.
This is part of the basic consumer guarantees that you get when you
buy something (at least in 49 states in the US).

This is fine. There are other licenses that don't allow selling the
software per se. The DFSG only requires the ability to sell it as
part of an aggregate software distribution. It does make it GPL
