Your take is so off the mark it points to a good bit of ignorance on your part. The mount of resources involved in training a legally viable model are enormous and well out of reach of any individual or even group of individuals trying to open source the problem. Also, Nvidias tool is a research tool. It's not retail software meant to give you the power of a self driving car. Alpamayo says as much on their git repo.
Can I use this model in production / commercial applications?
No. The model weights are released under a non-commercial license. This release is intended for research, experimentation, and evaluation purposes only.
So no, this is in no way a "simple" technology and it is not within reach of the average person to implement.
