I didn't take that in account because of the idea that the kingdoms don't fit the entire terrain. For instance, there is the City of Vale which is located at the west side. However, does that mean that the rest of the continent is empty? The girls said they were heading to a place just outside of the kingdom which was located at the east: Mountain Gleen. By the name, I assume it's located in those mountains outside of Vale. If that's the case then there is a chance I'm right an the Kingdom is actually only the City of Vale which is a tiny portion compared to the rest of the place.

If that's the case then Vacuo, Vale and Mistral don't have the same distant between each other. They would have to go through the rest of the continent just to get to the sea and then reach the other kingdoms which also requires them to go through that other continent.

As for Taiyang, that's what I assumed too before I heard that comment about Yang being trained by Qrow. But I just pointed that other possibility to aid Kunrin in this theory.
