Feudal society

But the bulk of the population, the peasants, or smerdy, seem to have been free men at the dawn of Kievan history; and free peasantry remained an important element throughout the evolution of the Kievan state, although bondage gradually increased. Soviet historians emphasized that process and considered the evolution of Kievan society in terms of the establishment of a full-fledged feudalism. But the prevalence of a money economy in Kievan Russia, the importance of towns and trade, the unrestricted rather than feudal attitude to landed property, the limited and delegated authority of the local magnates, and certain other factors
indicate that any serious discussion of feudalism in Russia must refer to a later
period of Russian history.

Please explain

1. Does having money economy mean that a society is not feudal ? How it works?

2. What is the difference between unrestricted rather and feudal attitude to landed property

3. What does delegated authority of the local magnates mean? Thanks for your kind help.
