One might also mention the usual example of attempting to legislate
physical reality, the "Indiana pi bill":


It may be hard to believe (whatever countries we live in), but dig
deep enough down through our interlocking systems of laws and treaties
and you eventually reach some underlying model of physical reality :-)

Example: If the ITU proposal were to attempt to relayer civil
timekeeping on Earth onto the length of the Martian day, one can be
confident they would fail.

The issue is how close is close enough?
