The problem with these services is that they're not portable and you don't realize it until it is too late. For example, there is this service called "Vudu" in the US that lets you purchase movies that get added to your 'library' or if you have the physical disc, keep a copy in your 'library.' Then you take a job out of the US and find you can't even access the service. So, buried deep in the ToS, you discover that you agreed to lose access if you leave the US. Meanwhile, you thought you were saving a few boxes worth of shipping by leaving the physical disks in the US.

Same with Apple. At the time we moved, we had a few movies in our library that wouldn't transfer to the new region. We had to go "buy" them again (at which point it would realize you already owned it and charge zero currency). FWIW, Apple has since fixed this and when you change regions, your purchases come over (mostly) without any issues.

If we could fix the region shenanigans, all of this would be fine IMHO. At least when it comes to digital content.
