I don't think you are dense, or at least that dense. But keep at it.

It is quite clear that you don't realize a "sheet" of spacetime with a
curvature decribing an escape velocity of c does not itself scatter or
emit light, such that it could be seen. Ilja places a surface above
the event horizon, and every bit of matter incoming must strike it,
and the energy of that collision is not "red shifted to
unobservability".

You clearly want to believe that we are safe from the LHC destroying
the Earth, because black holes do not exist. Whatever makes you
happy. I think it is not a problem, because Nature has already done
worse, will do even worse in the future, and I expect the Earth will
care not one whit how fast a proton or nucleus is moving. A tiny
black hole evaporates in a very short time, just as "dual to black
holes" do.
