I'm perfectly willing to rip DVDs and I have a seriously huge library of local content (~7500GB). I've been doing this stuff seriously for years now, so I have a very good starting point for not really having to download anything if I don't want to.
I do not ever torrent feature films. I only torrent TV shows for things that are obscure, won't be on DVD (most recently, the last 25 years of Nova documentaries), or that I HAVE to see right now (e.g. Walking Dead). These files tend to be insignificant in terms of my overall downloading; maybe 5GB for a season of a TV show at DVD quality, maybe 400MB for a single episode of an hourlong show.
Music: My taste runs to classical music, which I suspect to be a very low risk for downloading. A lot of what I'm downloading at this point are vinyl rips for things that have never been on CD to begin with. Were I downloading popular music, that would be the sort of thing I'd do on the btguard machine.
Streaming: I certainly can, but when ever possible, I'd prefer a local file or a DVD. I believe an average movie from Netflix is around 2GB.
