So you just add a tax on land ownership and do nothing about wealth concentration - and thus power concentration - and think it will magically work out? Those rich powerful folks are now just going to stop attempting to bend the rules in their favour? Those taxes would be gone within a year and all that's left is a Propertarian neo-feudalism.

You also skipped the answering the main part, a "Great Reset" that surely must be a logical first step to avoid undue advantage jumping over from the flawed past?
