Let's say that the telephone companies do manage to pay our congress to block full internet access.

What happens to gatekeepers who go agains the 'net?  What happens to parasites?  Whether censorship or access, the individuals and companies that developed and run the net will, like any other animal, re-evolve to isolate and finally destroy the parasites.

Our telephone system is vaguely 19th-century anyway.  Even Brazil's is more modern.

Just give 'em enough telephone line to hang themselves, and watch them end up behind their own gate as they attempt to put up a little wicket fence in front of a buffalo herd.
