It's worse than a chicken-egg problem because it's a triple-ended market: users, content sellers and content owners.
Netflix, YouTube, Hulu, Amazon, TPB, TV, theaters ain't the final word in content monetization (or lack thereof) and distribution (or also lacking). If say Netflix were to split up their business into b2c subscriptions and b2b2c fulfillment platform, more studios and others might opt to build their own marketplaces but use the fulfillment service... which strengthens Netflix's overall position and de-conflicts their interactions with studios because it turns them into potential customers instead of just adversarial vendors whom seem to want to charge too much for their catalogs. Let them find out how much it costs to build and promote a streaming subscription service, and then they may be more receptive to negotiating in reality.
