So, the HVDC systems us AC transformers to change the voltage at each end, rectify/invert to/from DC at that voltage, etc.
SO, if you want a DC tranmission/distribution/household use system, at each step you invert to AC, use a conventional transformer to change the voltage up or down, then rectify back to DC…
Why would this be better???
If somebody (say a Peer) really wanted to do HVDC, we could generate the DC by re-fitting the Hoover Dam’s powerhouse with Faraday Disks. I suppose said Peer would have a strong position in copper futures, of course…
