Emergency care people are required by law to treat anyone, even if they're
not covered (this gets frequently abused, of course).

They won't switch you off if the relatives continue demanding treatment.
It may be living hell on earth, but you will be kept alive.

If you have the coin, you can buy any service you need.

"Moving the brain" while keeping it alive is quite impossible with
current surgery. It is rather difficult to extract even a fixated
brain (a very different animal from live brain) from the cranial 
cavity without injuring it.

It wouldn't. Just leave the brain in its natural container, see
for details.

Gradual/incremental in vivo uploading is quite a way off, since requiring
medical devices assembled by NC-chemistry, aka machine-phase. Working
at below -150 C has definite advantages, since you can work with sections 
of cryogenic water glass, imaging from the surface down abrasively/ablatively,
and process data with macroscale equipment which doesn't have to be in situ.
