Crimes DO NOT require concrete damages. Civil claims do require concrete damages.

Being convicted of drug possession being one really clear example - there is often no need to even prove the person was aware of the existence of the drugs. Mere actual possession is usually enough (depending on the jurisdiction). And there is no need to prove the person intended to sell, distribute, harm, or even do anything with them. Even if the person literally was taking them to be destroyed, they can still be convicted of the crime.
