I suggest you do some more reading, then. In case you haven't noticed (and from the looks of your post, you haven't), the moratorium on taxing the Internet has lapsed (thanks to Congress). Moreover, the U.N. recently stated that they want to take control of the Internet...and all that that implies.
It's no longer the drumbeat of the alarmist...the nightmare scenarios of the U.N. in charge are starting to gain legitimacy among the sheeple.
Yes, I have read much on the topic of an email tax and it has proven over and over again to be bogus. Its completely unenforceable no matter who decides to tax it.
As for the rest of your post, control of the structure of the Internet itself rests with several multi-national corporations such as AT&T, MCI, SBC, Deutsche Telekom and others. The Internet exists in its present state because it generates cash flow for these companies. Take away the cash flow and shut down, or severely restrict the Internet. (Which may not be a bad idea; maybe a lot of us would get more done.) Just how is the UN supposed to wrest control from these guys? This all sounds like a lot of tin foil stuff.
And, the Internet is taxed in a lot of states. Texas, for one, has the Texas Infrastructure Fund which is a 1% tax that providers pass on to users in addition to sales tax. There are many other examples throughout these united states. The moratorium that Congress has yet to act on is a moratorium on sales tax for goods purchased over the Internet. The Internet itself and access to it has plenty of taxes in the US.
