You are sort of missing the point, i think.
Tesla is claiming that now is a good time to move to NACS because they already have 60% more NACS ports than CCS.
But this is not really right, because all those cars/charge stations also have J1772 connectors they are using and would no longer work.
So
1. Tesla is a lot less ubiquitous than they are claiming. J1772 + CCS is far more ubiquitous - by a factor of 3x.
2. You'd either have to retrofit or use adapters for all the J1772 stations as well (Yes, tesla ships an adapter, i know).
3. Nobody is going to do that.
