You're right, full nodes sitting on the network don't do a whole lot. It's important that many economically active users (e.g. wallets) are fully verifying though. Wallets based on a fully verifying node are less susceptible to attacks from miners. >It is just duplicating work that is being done elsewhere. This is the whole point of Bitcoin. If you only want the transaction to be centrally verified, you can use a federated model instead.
