Because the government isn't building them. They are Cray supercomputers, supplied by HPE. Not entirely built with standard parts. Proprietary interconnect and cooling system.

Infiniband is not a proprietary interconnect. Water is not a proprietary cooling system.

High scale is about using commodity components (hundreds of) thousands of times.

HPE Slingshot is not Infiniband and it is proprietary to HPE.

The cooling system is also proprietary to HPE. Not saying that other vendors don't offer their own liquid cooling systems.
