plows and mill stones and spinning wheels are excellent examples of exactly what a feudal lord owned. They owned the land, the major structures on that land, and the major implements on that land. If you wanted to use them you paid the lord in fees via goods, labor, etc. It's basically the gig economy - you will own nothing, your labor will be for his benefit, and if you want to keep participating you'll make it worth his while.
That did occasionally happen but I don't think it was the majority case by any means.
That being said, if we're talking about the lord owning the mill you labor at, how is that different than tesla owning the car factory you work at?
Tesla does not, AFAICT, also own the land you live on. They pay you in fiat currency that can be exchanged for other goods sold by any provider.
A better comparison to support your "capitalism = feudalism" argument would actually be the era of company stores and truck wages: https://en.wikipedia.org/wiki/Sixteen_Tons
