It would destroy the timescale. If you start with the whole earth's mass made of nothing but carbon-14, and let it sit for 1 million years, all of it would decay except for one atom, and that atom would have a greater than 99% chance of decaying. Two million years does not mean two earths. 1,005,730 years means two earths, and by 2 million years, you could decay all the matter in the universe from carbon-14 to nitrogen-14. That means that if there is supposedly "2 million year old", or "200 million year old", material that still has residual radiocarbon, it simply could not be that old.
