I agree it is not really Capitalism, but it is the ideology that most experts seem to agree has ruled over the world for the past 30 or so years.
More likely we'll see a society where there is no government but the internet is the interconnecting medium which handles commerce, justice, laws, et al - in other words, you'ld end up with a contemporary Tribal Society but under a name we don't know yet. Had Occupy Wall Street succeeded then it would had been "Occupyism" or "Anti-Consumerism"
Now that sounds interesting. Sort of like Bitcoin replacing conventional physical economic systems, Internet could in fact replace physical governments, especially as we move away from separate states into one global society without borders. But that is looking really far into the future I think.
