Earlier quoted context omitted.

Why would you use DC at all, and why would you put something in the middle? I don't think that makes any sense.

To up the voltage

You said that already, but why would that be a better approach to using a higher voltage from the start or using AC? This isn't exactly an unsolved problem.

Because of voltage drop.

You will have less loss if you correct for some voltage loss midway.

You lose more electricity if your line drops from 1000kv to 600kv than if it drops from 1000kv to 800kv twice, even if you count up conversion losd.

Megavolt range up conversion is rather inefficient (that's why HVDC links real efficiency is notably lower than its transmission efficiency,) but it will still be more economical
