Yeah but if you look down the axis of rotation you will have a perfect (to many decimal places anyways) circle... which was the demand.

That might be right.

But even then, the biggest black hole we think is possible measured down to the planck length gives you a number with 50 digits. And the entire observable universe measured in planck lengths is about 60 digits.

So how are you going to get a physical pi of even a hundred digits on the path toward arbitrary precision?

There is no contradiction here.
