I understand it completely, but personally it just wouldn't factor in my choice to UC, the possibilities of transferring are too slim for me to make it the deciding factor.
There is only one doctor at the hospital here and he is not close to being home birth friendly or even naturally birth friendly (he has been known to fire women for having a doula) but if I was to transfer I would still stand up for my rights... I also would only transfer for a life or death emergency (not just tired etc) so I would probably go there with the expectation of a very medicalized treatment because that is their speciality (which is why I would never birth there in a non-emergency)
wait, what? Dr's here can FIRE you? I've never heard of it happening, I just assumed they weren't allowed to!
Hmm, maybe I'll be a little bit more close-mouthed to my dr. Or more polite at the very least. Just in case.
ETA: I apparently missed this on my first read-through, I realize this is kind of a late response to your post :P
