What about capacitive and inductive losses. These are significant in AC transmission lines, depending on their construction. I believe that's why high voltage interconnects between different countries are usually DC and use rotary convertors at the ends.

The main reason for HV DC historically was that it doesn't require grids to be synchronous, or even of the same frequency. This is often desirable because a synchronous grid requires deep organizational integration. HV DC also lets you use mono-pole systems fairly easily, since they're single phase; sea or ground becomes the return path.
