The MCS (Megawatt Charging System) is also designed by a committee and has been adopted by Tesla for the Tesla Semi, so I don't see how this is even a relevant argument. NACS does only support single phase charging, while CCS2 can do 3-phase charging.
The only truthful argument in this discussion is that Tesla already have a huge charging network using their (previously) proprietary connector and automotive makers want to have access to this. NACS use the same signaling protocol as CCS, which is also why you can get away with a pretty dumb adapter.
It has the same physical limitations as any other cable. If you want to deliver high power at low voltage you need thick cables, there's nothing you can do to get around that fact.

CCS Type 2 is rated at 1000V and 400A, or 400kW.
