The third option is to adopt a coarse-grained gauge-invariant interpretation, according to which the representation relation between gauge orbits and physically possible states is many-to-one.
After all, isn't it fairly clear that the preferred interpretation of a given gauge theory is a simply gauge-invariant interpretation?
I grant that simply gauge-invariant interpretations are, ceteris paribus, to be preferred.
First of all, of course, we would prefer that our interpretation render the theory deterministic: that is, we would like to find a gauge-invariant interpretation of electromagnetism.
Thus, one would like to look for a gauge-invariant interpretation of electromagnetism.
There remains one further question: is this interpretation simply gauge-invariant or coarse-grained gauge-invariant?
