Theoretical entities called "black holes" cannot exist in finite universe (no matter the perspective changes that are applied). The result (if I understand it correctly) applies to a universe in which there is a single massive body and universe is eternal.
Hence, if time dilation exists (under increasing levels of gravity) "black hole" cannot form in any finite time. Since there are many massive bodies in our universe, solution to problem is not applicable.
So, in that context, "black holes" ARE GOSSIP!!!!
Let the "GOSSIP" wars commence.
Other than that, I think you make some very salient points, especially about the approximations that we make and the validity of those approximations to the specific applications/situations being studied.
