True. But while a high voltage converter might be expensive, it's far more efficient and would pay off costs over the duration of the life of a home. Having a single one of those per home should surely be a net win. The utility is responsible for high voltage AC transforms down to the home, and the homeowner fronts the cost of the centralized expensive but efficient converter to power the DC circuit within the home.
If solar and local generation are thrown in the mix, they bypass the converter and directly power the home circuit.

Why wouldn't this be more globally optimal?
edit: derped the converter
