There's no reason a BitTorrent movie downloader couldn't be made just as easy to use as a Netflix downloader. If one doesn't already exist, it's not because DRM is somehow stopping it.
It's not just reasonable, it's easily demonstrated in practice, when goods released with DRM are pirated almost right away (with DRM being scraped off). Sophisticated pirates are needed to break DRM. Unsophisticated ones get it from them without any hassle. Which means that DRM has no effect altogether except on legitimate users!
I.e. the vast majority of pirates never deal with any DRM, and experience of legitimate users is always degraded by it. It's pure common sense that removing DRM would always improve any service. And the fact that it's not happening is caused by other reasons (see above).
