GR describes a classical theory. Quantum gravity shouldreduce to GR in
the right limit, but won't describe a continuum.

If there is a non-infinitesimal quantizing of the curved
space-time interval then this shortest distance of events
would seem to eliminate anything happening on any smaller
scale. NOTHING COULD HAPPEN THERE.

Ever heard of the Planck length? That's the length scale onwhich
classical gravity has to break down and only be explainable
by quantum effects.

Ever hear of anyone doing an experiment that reveals what happens
at the Planck length?

You're charging at windmills. And you don't know what you're talking
about.
