This is obviously wrong in principle. The way music downloads work right now is exactly what I've been describing - music from iTunes or Amazon comes without DRM, and they allow me to purchase songs wherever I am, from wherever I am.
If your argument is those DRM-less music files don't make it onto Torrent sites, you're mistaken. Nevertheless, they sell them without DRM, because customers pressured them into it.
I buy it on iTunes, I put it into my music folder, copy it around to all my machines, it's just fine.
So I'm a German national being in France right now. If I decide to buy some music from iTunes, I click on the "buy" button and stuff starts downloading. However, if I try to purchase a TV show, it starts out by showing me only German shows. Deep down, I can find outdated US originals with subtitles - which is the best option they give me! What happens when I try to actually purchase one? "There is a problem with your iTunes account". Oops, I'm currently in the wrong country, no show for me! There is no getting around the fact that this sucks, it sucks needlessly, and to the detriment of everyone involved.
