Well in your case you don’t need the subscription at all, apart from some minor things the subscription won’t do anything for you.
But I do all the things you’re not doing. I share my server with dozens of friends/family so I need remote streaming. I can watch shows on my own server no matter where I am (at work or when visiting relatives, or even on the phone on the train). And if you streaming on the phone or with bad internet in general it might sometimes be a good idea to reduce quality to save bandwidth.
