Good point and this is a core art of Netflix's strategy for its own content. It's not going to happen any time soon with content from studios and other distributors though, because international distributors usually buy the rights to a film for a 10 year period. Except for the biggest 6, most film distributors don't have multinational operations and even the big 6 don't have offices in every territory, so they can't just wave magic wands and abrogate existing international distribution contracts.
