Feudalism didn't end in violent land reform, it largely ended after a pandemic that killed off a significant number of the workforce and it became a sellers market for the serfs. Turns out we just crippled the world economy for decades avoiding the sequel.
There is more to human history than Western European history. Feudalism has emerged and failed in many places.
not feudalism, because these corporations can be well regulated and renters rights protected by law.
Not if the corporations write the laws.
"not feudalism, because these lords are men of God", etc.
lords claiming some rights supposedly ordained by god is quite different from a democracy that enacts laws that protect the rights of its citizens, especially the weaker ones. just because that doesn't happen in the US doesn't mean it can't happen, because it actually does in most of europe and other countries too.
They really aren't that different. Laws are twisted and changed and ignored by powerful people, whether those laws are divine or constitutional.
