Dear Principled,
"Who would eliminate the income tax without a replacement?"
If the NRST legislation were initially passed, it could be passed with the caveat that it would not take effect until the 16th Amendment was repealed. Just change the legislation to state that the NRST will not be put into place, that no national sales tax will be collected, until the 16th Amendment is repealed and the federal government is stripped of any constitutional authority to tax our incomes.
In that case, the income tax would be replaced with the NRST upon the repeal of the 16th Amendment.
If you want to push the repeal first - without first passing a form of the NRST legislation, then the repeal amendment could state that repeal would not be effective until an NRST was put into place.
Actually, I think you'd likely get more support for the NRST AND repeal of the 16th Amendment if it were done this way.

I agree with you on this point.
