I still find it hard to believe that it's cheaper to pay someone (per the article, for transport from UK to US) $20k to fly your plane, than it is to dismantle and put it in a shipping container, and reassemble it on the other end.

Maybe I have a naive understanding of the complexity of taking a light aircraft apart? I do know though, that shipping a container from Europe to Australia (!) runs a bill of around $5k, and I can't imagine the plane referred to in the article taking more than two containers.
