Naw, I was jawin with (IIRC) CHIEFnegotiator (now deceased) for bloody ever about this almost a decade ago on FR. It got tiring.
An NRST is a wonderful theory, but the size of the markup to support current levels of Federal spending would make it so attractive to avoid paying the tax that the level of intelligence the IRS would need over every human transaction to enforce its collection would be an outrage. A few pennies on the dollar works, but once over 10-15% and substantial numbers of people will cheat. State sales taxes are already almost there, at least in California. Bootleg liquor and cigarettes are already common. About the only commodity one could tax that way and collect it reliably would be energy.
