There's already so much capacity sunk into the ground you wouldn't need to dig for another decade, you could just upgrade equipment on the end-points. Expensive but a lot less work than getting permits and ripping up roads.
If the rumors about Google are correct, they may be in for a rude awakening.
Incidentally, I hope the ISPs that own everything lose their common-carrier status when they start disconnecting people over copyright claims. Look at the rage that copyright enforcement has when audio is stripped from YouTube videos. I don't think people are going to be happy when their net connection is cut off.

(I see from the website of Megapath, which is what Speakeasy seems to have morphed into, that they do actually provide broadband, but it looks like "small business" broadband--i.e., priced too high for a home user. Their offerings at home user prices are basically DSL.)
I doubt it, but I wouldn't be surprised to see small scale upheaval given enough brouhaha.
