Just have separate prepaid cards per country? You're already paying the price for that country's content selection, so Netflix should have no issue giving you access to that content either.
That still allows easy bypassing of the country restrictions. If you're a local pay TV broadcaster who has paid a premium price for a show that is particularily attractive in a given country, you are not going to permit Netflix to sell the country you paid exclusive rights for.
Netflix could trivially buy the rights cheaply for a small country with a tiny economy and then use these cards to sell to the US or other major countries where the rights could cost a thousand percent more.
