Speaking to delegates at the summit during the trip, Carney also emphasized why Canada is so focused on Europe.
“As the rules-based order ... is rebuilt, it will be rebuilt in Europe,” Carney said.
I suppose that makes sense. In business, when trying to compete with a well-established monopoly, one of the most crucial things to consider is brand recognition, and the EU is, at this point, the global entity with the most "brand recognition", out of all the countries/organizations that still believe in the concept of the rules-based order.
Yes that's my guess as well: the prospect of stealing even a fraction of the business that Amazon does would probably make the whole thing worth it, and to that end, the main thing eBay brings to the table is the kind of pre-established brand recognition that money can't buy.
