I'm not sure how we're managing to agree so much on overall direction/motivation, while seeming to contradict one another.

Yep - and if the screen is "just a screen" (i.e. has no file manager or other media-interfacing functionality on it), there there will need to be some _other_ computer in the stack of "computers all the way down" to provide the media-interface. For me, Kodi does that job perfectly well, but it doesn't work well for everyone.

Yes, this is an uncontroversial statement of a distasteful truth.
