Because nation states have various censorship requirements for these services to continue to exist in their jurisdiction. "watch content not available in their home country" is the key phrase here. If you want to watch something that has been deemed 'unfit' for the masses by the local law, Netflix has to follow those laws. Licensing agreements are another problem, but this one looks to be specifically about catering to local law. There are probably also issues with production company contracts, entertainment union contracts, etc even if Netflix "owns" the show. Wikipedia lists four different production companies alone for "House of Cards." Then there are probably issues with at least SAG-AFTRA, WGAW, DGA, ASCAP for music/score licensing, etc. These are all stakeholders with, usually, strong contractual rights to the IP.
