There's no such "space" at all. This whole idea that trans women are somehow monopolizing spaces that "rightfully belong" to cis women is just a transphobic, hateful slur; especially so when the attack is so clearly targeted at a single, vulnerable trans person. The block was absolutely warranted; it was an egregious violation of a "no personal attacks" rule that's been there since the beginning.
Not going to entertain the plenty of your tangents, just going to say this:
you are wrong, obviously these spaces exist and I'm confident this comment refers to such one, because the context makes sense this way (Occam's Razor), so the block was not warranted at all, not even in the slightest.
