I agree with you but a better explanation I think is. Raft/Paxos is to make sure majority of the replica for a partition have the latest version of the data and that you can keep writing even if minority of nodes in that partition are unavailable. while still giving guarantee that no write get lost and all read reflect the most recent write. While 2PC is to write 2 records atomically when the 2 record are located on 2 different partitions.
