Perhaps I've not made myself clear, but my basic complaint is that your approach does not actually ignore boundaries, be they state, county, precinct, etc. It creates a condition wherein the choice of a smaller group's majority is converted to that of a larger group's majority.
If the system were restructured so that there was only one group, citizens of the U.S.A., then every vote would count equally right up until the end of the voting process. That's not what NPVIC does.
What I see you doing is going for what's right in the wrong way; specifically, subverting the Constitution. That sets a really bad and dangerous precedent but it's what a lot of USAians do these days. There was a time when we did what was right, in a manner that was right no matter how difficult.
