Abolish and replace with what? How do you ensure that the outcome doesn't resemble post-soviet privatisations that are impossible to get undone within 100 years

Abolish and replace with what? How do you ensure that the outcome doesn't resemble post-soviet privatisations that are impossible to get undone within 100 years, if even that. It looks great on paper, until it doesn't in practice when it turns out there are bazillion ways to game an anarchic system which some "architect" assumed will self-govern. Discarding zoning, I can already see public parks getting converted to smelly pig farms and for profit cemeteries. Land is leased for infinite time durations, so very very hard to undo.
