So, by definition, a Docker pull client command actually needs to talk to a Docker daemon, because the Docker daemon assembles layers one by one for you.

Think of it as a POST request - it's causing a mutation of state, in the Docker daemon itself. You're not 'pulling' anything over HTTP when you do a pull.

You can pull all the individual layers over REST from the Docker registry, but that won't actually be the same semantics as a pull, because pull is an action that specifically tells the daemon to go and get all the layers for an image you care about.
