Not really. Smart contracts ensure that if all the conditions are met, the contract will be fulfilled. They achieve that through decentralisation: no one person can decide whether or not it will be fulfilled.

No real world contract can replicate that - you have to go to court to enforce a breach of contract and it isn't certain you will succeed. Even if you succeed the other party can refuse to comply, and then you need to try to enforce, which also may or may not work.

The oracle can lie and be unreliable too. It would be great system if you mangaged a video game where the currency system can see the objective state of the world, but ethereum can't, needs oracle(s).

In both cases you basically rely on reputation of oracle, or escrow company in case of old money transaction, to have high degree of safety.

yes it can, if that product is in the chain iteself. Not all contracts are external, most are not.
