There might be another motivation. Personally I suspect any results which
give a physical infinity are indicative of incorrect theories, just as
infinite blackbody radiations indicated faulty classical thermo, which was
solved by the ad hoc introduction of quantum.
Of course blackbodies were observed to be finite, while evaporating black
holes haven't been observed, so my suspicion is a matter of faith. (Or
prior.) But still. You tell me there's a naked singularity, or even a
singularity, I'll assume your physics are wrong.
(Is there any evidence for black holes with singularity at center, as
oppposed to just some mass with a superliminal -- or even barely subliminal --
escape velocity?)
(I remember _Frozen Stars_ suggesting that proper GR black holes never form in
the reference frame of an outside observer, since the time dilation of the
infalling mass keeps increasing and you never get to see it cross the event
horizon.)
