Things are not black and white.

There are certain things that can be more easily audited, verified or enforced on-chain. For example, payments could be automated (potentially based on verifiable data), or secured lending could happen programmatically.

At the end of the day, yes, you still want to have legal enforcement, i.e., if someone defrauds you on chain, that's still a crime and should be enforced, or if someone fails to deliver, you should still have a contract claim against them.
