I am not really sure what you're talking about RPC is "remote procedure call", emphasis on "remote", meaning you always necessarily gonna be serializing/deserializing the information over some kind of wire, between discrete/different nodes, with discrete/distinct address spaces a client request by definition can't include anything that can't be serialized, serialization is the ground truth requirement for any kind of RPC... a server doesn't provide "an object" in response to a query, it provides "a response payload", which is at most a snapshot of some state it had at the time of the request, it's not as if there is any expectation that this serialized state is gonna be consistent between nodes
