I am checking if the C++ representation has not already been destroyed.
Which for all practical purposes means that the C# object is null.

That is not possible, we are creating a release quality product. I can't

Is there a way to make the compiler give compile errors when the user is
about to use the comparison operator? Disabling it completely is at least
better than wrong behaviour.
