If black holes don't exist then neither does the cosmic horizon?

So according to Stephen Hawking, non-penetrable event horizons don't really exist.

So by the same argument the cosmic event horizon can't exist either right? Only an "apparent" horizon which may hold information from outside the visible Universe for a short while until it enters the visible Universe.

The cosmic event horizon is often described as like living "inside" a black hole. But since black holes don't exist any more then this also means that we are not cut off from the rest of the Universe by a cosmic event horizon?

Have I got that right? What do you think?

I think the critical notion is that information is not lost when something crosses that horizon.
So anything that was ever within our visible universe has never been lost without a trace.

Well that's good then. It's good to know that all those galaxys crossing the Cosmic Event Horizon are not lost forever! :)
