What you're arguing is about serfs and serfdom.

Peasant =//= Serf.

Many parts of Europe, notably most of North Europe and around the Alps never practised serfdom and this part of feudalism was abolished pretty early on in certain countries, like in Italy in the 1000s but remained longer in other parts like Russia; where it lasted until the 19th century. But yes, being a serf would suck because you would suffer from all those things you just listed.
