Hard disk storage isn't getting cheaper at the same pace as earlier(before the Thailand floods 10 to 15 years ago IIRC). Bandwidth is also expensive, especially across the world. Microsoft threw in the towel in a related space(live streaming) with Mixer. Twitch wasn't really profitable for a long time IIRC, if it now is(even after adding a lot of unskippable ads and adblocker blocking). Kick is bankrolled by online casino gambling profits and is probably a huge money sink.

If something was feasible, surely the people who hang out on HN would be all over it trying to build something. Even if something does get built, it will go the same route eventually.
