Bonald of Throne and Altar is aiming to produce a "neofeudalism", which should be interesting. He opens with the challenging line, "We shall never truly defeat socialism until we abolish private property."
To be clear, my own view is different: the problem is not that we got rid of feudalism, it's that the one last obsolete feudal institution that needed to be destroyed unfortunately remains.
I don't think feudalism works at all outside a primarily agricultural economy. If the government is made up of landowners who have the bulk of economic power, then their interests are both fairly uniform, and fairly consistent. Compare with the present day, where the interests of civil servants, bankers, professors, property developers, union leaders, arms manufacturers and media providers are all at odds, and vary rapidly, meaning that government made up of those groups is mostly concerned with internal disputes rather than overall effectiveness.
