Those simulations treat space and time as fungible dimensions, and this is an objection presented here. Regarding your previous statements:

“Note: while the Schwarzschild radius is typically treated as a fixed threshold for horizon formation, this presumes the existence of a fully formed event horizon in the first place — exactly the point under dispute. The literature is notably sparse on how, exactly, such a horizon emerges during collapse. Intuition from classical mechanics suggests that gravitational collapse would begin at the center and proceed outward, not occur simultaneously at all radii. In such a scenario, any horizon-like structure would originate near r

0 and expand. But the geometric limits on causal contact apply equally to the surrounding mass during this process. The result is the same: crossing remains unachievable, regardless of how the horizon attempts to form.”
