If we discover room-temperature superconductivity and it is industrial-scalable, I could see DC taking over AC transmission lines.

But right now, resistive heat losses make DC a silly solution. That’s why we rectify only when the energy reaches “the edge.”

Ohms law is the same for AC and DC at any given moment in time. That is, in an instant where an AC voltage in a wire at 120V, it will have identical resistive loss as DC voltage at 120V.
