Why can’t/doesn’t Ravencoin have smart contracts?

Every time someone brings up Ethereum or Ravencoin people are like "yeah but they're different projects, rvn no smarterino contracterino".

Why is this, though? Do you need smart contracts to be written on the blockchain base code from the beginning? If RVN already has built-in asset creation and atomic swaps are being made then what does it need smart contracts for? Aren't SCs exploitable and, at some degree, potentially harmful for users due to scams like honeypots?
