quite a big assumption to make, whom will require this, and more to the point,
how does that need in any way legitimise putting GPS coordinates in a packet
header?

Rather than comment on this immediately, I will first introduce the context of
a quote you have made further down.

If you can arbitrarily alter the coordinates, the copyright enforcement aspect
that you are proposing is violated. If you wish to declare exceptions where it
cannot be altered, the privacy assurance is violated.
In any case, it loses all value at the nexthop; there will be absolutely
nothing preventing another router from mangling the value, whether
intentionally or due to accidental corruption. Not to mention someone
elsewhere simply firing out a packet spoofing your source address.
A proposal such as this goes far beyond the intended scope of IPv6; if GPS
coordinates are acceptable, where shall we go next? Social Security numbers?
Reductio ad absurdum.
