It can't happen. That is just a mathematical illusion. Relativity completely disregards the one way speed of light, so it allows to change it freely when changing the frame of reference getting faster in one way and slower in the other way as necessary. That lack of consistency results in causality violations and singularities. Both can't happen when using only one frame of reference that keeps the one way speed of light constant and the same in any direction, like the microwave cosmic background.

Where do you take this value, infinity, from ? One has no insights beyond the event horizon, which has a finite diameter that is greater than 0. One can in theory keep a record of all matter that ever ended up 'inside' the event horizon. The record will always imply a finite mass that too is greater than 0. So the density is anywhere between pretty dense and infinity. Likely closer to pretty dense than infinity. But since we have no insight beyond the event horizon for all practical purpose is maybe whatever floats your boat.

>(2) Black holes are, by definition, objects massive enough to overcome the speed of light
>(3) GR math predicts infinite density
>(4) We have no understanding of how that would actually come into reality from standard objects
So either (a) GR's prediction is correct and we just lack understanding of how infinitely dense objects can form, or (b) GR, being a mathematical abstraction, breaks down when dealing with black holes and shouldn't be treated as gospel. Really it's a issue with calculus being used to describe the interactions of discrete particles; it might give a very good approximation but you can't treat the mathematical notion of a limit as itself being descriptive of nature.

think about how atoms which are usually pretty hearty and massful, now think about how they can transition into a gas and even a plasma with enough heat, atoms have a lot of weird states they can exist in

and so anyways the universe just has another state of matter that is blackhole, where mass gets converted entirely into energy and exists in field form, its really not that crazy of a concept

At the center of a black hole is really just a clump of degenerate matter. If you could visually inspect it as something other than perfect blackness, it would not appear any special. It's just a quark star but more extreme. The ball has a definite (i.e. finite) extent and density.

It only breaks down when using the frame of reference of the object falling into the black hole. When using the frame of reference of the CMBR there are no problems at all, no singularity, no crazy stuff going on. Nothing can get inside the old event horizon, nothing can get outside the old event horizon, matter just gets spread all over and a new event horizon envelopes the new matter acquired. Is like an onion with event horizons all the way down.

Yes it is. This is why you may sometimes hear the phrase "unified theory of physics/gravity/everything", a model that can hold up on every scale of the universe. It hasn't been accurately devised yet, which is why relativity, classical, and quantum mechanics are what we have to work with in their respective scales for the time being.
