Of course they won't give you thousands of dollars of inference for a couple hundred bucks without making sure you're properly tied to their walled garden.
Yeah, of course Dario and any other Anthropic spoke person will vastly exaggerate the capabilities of their product and promote vibe coding and now "loop engineering", just like Coca-Cola would love for you to drink gallons of Diet Coke everyday, just like Oracle some twenty ago promoted for Enterprises that they could just use Oracle Databases to serve web applications right from the DB, as this would force you to use more CPUs and Oracle DB is licensed by core.
The business model for inference is metered usage, more usage => mode money. Again, the subscription model is just a bump in the road to acquire customers, once you're metered, the more you use, the better for anthropic.
Why people get surprised with that stuff?
