One answer is that all you wanted was bright, sixty inch monitor for your living room, into which you could plug your HDMI sources, but all you could get (subject to various other constraints: price, quality, availability, non-smart features you do care about, ...) was a smart TV, whose "smart" features you explicitly don't want.

You don't have to use every feature of something for it to make sense. I have a "dumb" TV. It has built-in speakers, but I don't use those. Volume is set to minimum. My streaming box connects to decent bookshelf speakers.
