It's not that everyone can or wants to run their own Plex setup, it's that the Plex model, once set up, is much more consumer-friendly: Get the shows you want, don't care about the distributor. It's probably naive to think that would work for a bunch of reasons (Who exactly runs this? Are they a for-profit monopoly now? Who will fund the content if there's no monopoly rent?) but I don't think it's crazy to imagine a service that works more like it. We went to all the effort of unbundling cable and now we just have a different set of bundles. It's a little better, but they've fallen back on old habits.
