Yeah, thankfully I said real-world communism. Utopian communism would indeed be great.
In feudal society, the noble owns the serfs. The serf cannot move without the noble's consent and is tied to the land in such a manner that, if the noble decides to sell the land, the serf on the land are sold too. They have to work the lands of the noble before their own and have to pay a tax on what they own to the noble. While they own some small tools, like pots, needles, tools for churning butter and other small farming tools, the biggest tools were often owned by the village as they were too expensive for the single farmer. Some other tools were instead illegal to own, a famous example was the grinding stone, which was illegal to own, since you HAD to go to the noble's mill to transform your wheat into flour and then bread. This was because you then had to pay a tax to the miller and a tax to the noble in order to mill your wheat.
So, in essence, in feudalism a serf did not own their land, did not own their labor and was not even free to move. So much better, right? /s
