You did a good job describing constraints Uber has in order to deliver a product to customers. From your description there might be good reasons for those constraints such as anti discrimination or price stability. But even for "good reasons" it doesn't absolve Uber of liability for treating employees as contractors.
This comment seems to contain a non-sequitur; you argue in favor of one thing, then make a tangentially related assertion (that Uber drivers are employees) with no argument in its favor.
