Well, but that's due to a lot of problems specific to the media landscape. Netflix started as an afterthought, the big media companies viewed it as a sideshow or as a stopgap measure while they made other plans, so there was a honeymoon phase where it was cheap and had a ton of media.
Most new entrants to the market are themselves media companies, so with each one the media landscape gets fractured. They're able to leverage popular content (over which they have a monopoly) to lure customers and raise prices. There's not many of them, and the barrier of entry is almost impossibly high (step 1: develop a 50-year back catalog of beloved films & franchises...), so the market is insular.
Compare with music, where there's a ton of smaller labels, and the barrier of entry is much lower. Streaming companies compete mostly on price, interface & experience.
I think the problem is kinda inherent in the market, and Netflix was just an anomaly because it caught the media companies flat-footed. You would need openness and competition on a much more fundamental level to solve streaming video media.
In the meantime, simple and open web payments could solve for music, podcasts, prose, reporting, art, etc. And hey, maybe somewhere in the process you could see the birth of micro-studios.
