So, given the size of a typical freighter these days, what's so hard about imagining one with enough wire in the air to make that happen for whatever political or commercial reason?

I'll freely grant that a 600' tower over a really good ground plane (like say the sea) is going to be way more efficient than anything I'd come up with. The same thing would apply to a matching network made of coils you can stand up inside compared to anything I'd make.
