Correct, but it's the fact that I can't possibly use it, even if I don't want to. That's what makes it scarce. That's what makes it ownable. Once I own it, I get to control the use of it, even if I'm not using it all the time. Of course, this assumes that things have objectively defined uses, which is false. Maybe I collect beds. Maybe I derive joy from knowing I have a clean bed with pristine sheets on it. In that sense, I'm always using it and you would be depriving me of something just by laying on it. However, as mentioned already, that's irrelevant.
