Fraud proofs are extremely important from a security perspective. The network as it exists now places too much trust in miners. Creating a way for non-full node clients to reject chains with contain invalid transactions regardless of how much hashing power produces the invalid chains is essential for the security of the network. Adding a fraud proof system into blocks means that other features, like committed UTXO sets, become less unsafe to deploy. Solving transaction malleability is a very nice to have feature. A scalability solution, IMHO, is "how do we buy some time to allow continue usage growth while working on creating a situation where it becomes safe to eliminate maximum block size as a consensus rule?"
