Actually, fiber can be run anywhere up to the building service entrance (the box on the wall outside). Look into the FIOS services available in some other parts of the country for an (incredibly customer, and 'net, un-friendly) example.
Fiber could easily be run inside the building too, but the the customer premises equipment (CPE) is all designed to expect coax connections, so it's highly unlikely you'll see fiber inside buildings anytime soon (then again, I'm not all that good at predicting the future, it could happen next week).
The big problem in getting fiber closer to the end user in the US is the huge amount of installed fiber, and the stupidity with which it was installed. Rather than install conduit, which would facilitate repair and replacement, nearly all cable (of all types, video, voice, and 'net) in the US is directly buried in the ground, so it has to be dug up to be replaced or repaired, and digging up streets (most of it is underneath streets and sidewalks) is insanely expensive (a single segment ranges from $10,000 for a small fix on a small street to over $1 million for a full block-long segment on a major street or highway in a major city center).
Since the cable companies have all decided that there's no *increase* in profit from upgrading networks, they don't bother to upgrade unless a given segment is causing too many maintenance problems, and then they only upgrade if they can't cheaply repair it (one of the reasons my connection drops whenever the outside temp exceeds 105, the lines are junk, and Cox won't replace them until analog video starts failing routinely).
Even when these companies do upgrade lines, they still take the stupid approach of directly burying the cables, since it's cheaper. They never seem to comprehend that paying a bit more now (conduit-bury is about 3 times the cost of direct-bury) will save immensely the next time the technology causes major changes (not to mention the ongoing savings in maintenance and improved service quality).
