I think the use cases of FHE are much more limited that you're thinking, specifically because it allows you to execute code on someone else's machine without them being able to see _anything_ about the data they're operating on, and send the results (which again, don't mean anything to that machine) back to you. So, for example, you could mine cryptocurrency on someone's computer, but the only benefit you get over running FHE-encrypted code on the client machine over running it on your own server is compute cost. It wouldn't be useful for e.g. DRM.
