Decentralized exchanges and smart wallets are useful applications of smart contracts. A smart wallet could include multisig functionality, estate management functionality, etc. For example, a friend has a wallet that will automatically be released to heirs one year after his attorney releases it. Of course he is able to cancel the transfer at any time, if he's alive. Is that a perfect system? I dont know. But it does sound useful. It's definitely true that many ridiculous and farfetched bad applications of smart contracts have been attempted or proposed. None of these have any bearing on the utility of smart contracts.
