It has always surprised me that the 'free world', NATO countries, developed countries (including Japan, Taiwan, Australia), however one wants to call them, do not have at least free trade, if not free movement of people and capital, between them.
A travesty, IMO. And a great loss making us all poorer. Not a patchwork of point-to-point free trade agreements, but several hub agreements that countries join, and, in time, the hubs agree to free trade between them too.
