"It’s not possible to use the equations of GR to show that matter can fall to an event horizon in finite time, from any frame of reference, because it’s possible to prove that the matter cannot reach the event horizon in finite time for at least one frame of reference."

A 'finite time' is your local time Android, the one you measure with your wrist watch. Assuming that you can pass a event horizon without tidal forces and spagettification it will run out for you, same as it will eventually for us all. But relativity does not state that this local time measuring is a illusion. Instead it define this type of time keeping as your 'proper time'.

When Einstein referred to time as an illusion he did not refer to the fact that we all live a while, to then die. Instead he was referring to a measuring on a whole universe in where we find time dilations. From that 'eye of a God' time seems an illusion, but for you locally it will keep you centered to a same life cycle as it holds us all.

It's what I call the 'container idea', and how you may want to define that container.

There is nothing stopping you to pass a event horizon, but what you will meet inside it depends on how you define its physics. If you expect the same physics as outside you can define different types of black holes, some in where you might survive, most that you won't. If you think of it as a singularity, no information let out? How will we ever know the physics inside them?

If you consider Hawking radiation his ideas, as far as I get them, also goes out from a container definition in where singularities is a part of a common cosmos, universe. That's how those virtual particle pairs can become real, as well as 'split' the one surviving being in a entanglement containing the same information as its annihilated twin inside, or at, the event horizon.

Most of our ideas presumes preexisting dimensions and commonly shared containers.
