Okay, so maybe not the best analogy. Contact access expiration via git is far more primitive, sure - if you have access today you can clone a private project and have a snapshot of it in that state, once your access rights are revoked you just won't see any further work. Unfortunately, this 'freedom' leads to far more problems than it solves - horrible corporate bureaucracies around where you may or may not check code out to, remote wipe capability, contractor laptops, etc. There are many real-world use cases where, in order to accomplish the completion of a project, you need to provide an external resource with access to sensitive data for a limited amount of time. Think manufacturing, commercial video production, medical data, game development - pretty much anything where you outsource a specific phase of product development to a third party. Without DRM, these workflows are limited to online-only, where assets are streamed and can't be stored locally. This is a dealbreaker when, for example, you need to send part specs to a manufacturer in the middle of China.
