Reasonable man licence

Would it be possible to word a copyright licence such that the user of the copyrighted material is required to pay a royalty that a reasonable man would consider adequate given the benefits that the user derives from that use?





Although subjective, this would be a perfect sliding scale rather than the abrupt contrast that occurs in the free for non-commercial use licencing model. It would be similar to donation-ware in payment mechanism, but has more teeth: there is an obligation to "donate".
