Not true. This is easily seen by interchanging black hole and observer.
It is also seen by noting that the existence of points of the manifold
between singularity and horizon implies that they do not intersect
(which you apparently call "congruent", you misuse this word) -- this is
independent of any motion of either black hole or observer.

And the singularity does not "produce" the horizon, they are both merely
geometric properties of the manifold....

The only possible "proof" of the nonexistence of black holes is an
exhaustive search of the universe. Good luck....
