I agree that there are a significant number of US households that do not have as of yet have the internet - probably as high as 20% based on extrapolations from the 2009 Nielsen's national TV panel study. That is also completely irrelevant when evaluating Ubisoft's decision.
Here's a better question. What percentage of
PC gamers do not have access to the internet? Only 8% of
PC owners did not have internet in 2009 (same study) and I would argue that the vast majority of those are unlikely to be part of Ubisoft's target demographic based on both age and income demographics. Of the remaining fraction of PC owners who are gamers without internet (2%?), there will be yet another (large) subset that will be unable to play Assassin's Creed 2 based solely on hardware requirements.
The point that I am belaboring into the ground here is that once you filter for Ubisoft's target demographic, it is entirely reasonable for Ubisoft to assume that they have internet access in their primary residence. The tiny fraction which will be overlooked are
negligible next to any real gains made by Ubisoft in capturing supplier surplus.
Inconveniencing travelers is the more credible downside here. Sitting in a motel room on a business trip is the perfect excuse for some singleplayer gaming, and there is no question that Ubisoft's decision may cost them a few sales from semi-frequent travelers. However, the people most likely to travel are also the ones most likely to have contingency plans for connectivity such as a smartphone they can tether.
I can also cite my own contrasting anecdotal evidence. I've been on perhaps a dozen trips to several countries over the last two years and have had access to my Steam library at every single location. I even had WiFi access during the last plane trip I took.
Ultimately, I have zero problems with requiring internet connectivity and an account for even singleplayer games. This is not only an excellent DRM method but much preferred by myself to install limits or even simple disc checks.

Consider that disc checks are in many ways a more severe limitation. It would be easier for most people to find an internet connection while on vacation then it would be for them to bring their entire game library around with them.
