TJ, you missed FACT#1, ASSUMPTION#8, and CONCLUSION#6.

You're right, we don't care about "negative groundspeed" at all. All we care about is airspeed.

However, if the plane's wheel bearings impart sufficient friction to the aircraft, then it won't ever develop enough airspeed to take off. But, IMO, that would be a very poorly designed aircraft.
