Sounds reasonable to me.

But also what the fuck happens to the core of such a planet when that happens?

We aren't actually sure what gave our core the spin it has, right? I'm not fully awake yet but I think it's plain where I'm going with this.

It's not plain to me where you're going. But the answer about the core of a planet engulfed by the sun is that it vaporizes eventually, just not right away.

We are, it’s from the conservation of angular momentum. The material that made our planet also had a non-zero angular momentum.

No we aren't. That's a theory that barely fits the lower bound of what we estimate the spin of the core to be
