It’s not necessarily cheap or convenient, but building a physical collection of Blu-Rays (or DVDs if quality isn’t priority) is something that can’t be taken away.

Add on a compatible Blu-Ray drive to your computer and you can even rip the digital files yourself. It’s taken me a few years, but now I never have to worry if my favorite movie is available when I want to show a friend. It also makes them easy to loan.

You don’t need a new system to do this and in fact can do it yourself. The issue comes in with signing up for new accounts, etc. Unfortunately there’s all sorts of different domains that emails can come from even with a single provider.
