The problem with Urbit used to be that each node was permanently bound to a single parent and "lords" had too much control over their "subjects", including things like kicking them out of the Urbitverse. That was changed so AFAIK it's no longer a concern. Most P2P systems are completely different because nodes can use any relay and relaying is separate from identity.

A planet has just one Star that sponsors them in Urbit, but as a planet, you can choose to leave your Star and move to a different Star.

So you can also choose a different relay in Urbit. And yes, your Planet address is spawned by a Star, but you do fully own your address. It is separate in the sense that you can move it elsewhere.
