There is no need for hostility my friend. I offered a question as your take on Lords providing some sort of service in return for goods from peasants is a take that is mistaken on many levels as regards to the concept of feudalism.

Simply put a lords "claim" to a peasants food was "I am instated by God" and "I let you work my land and you give me your food". Rather your take on peasants providing food for a ruling caste is better described as manoralism and really has nothing to do with the term feudalism, as that describes the relationship of vassalage and should be further distinguished by geographical constaints, as feudalism in England is different from France, and the rest of europe.
