The only thing seckimjohn showed is that contracts, paper or "smart", are only as good as they're written. Since contracts such as _red gave, "we are friends, this is our company, we share the EBT equally", exist right now, it's a perfectly realistic use case for a smart contract. Hell, I'd even do that for a small project.
Smart contracts being fixed and errors being exploitable is a valid criticism but it's not the be-all-end-all argument for them to have no real world applications.
