Of course the devil is always in the details. Overnight you’d have people selling square foot parcels in the countryside to urban dwellers, though probably not for long. In these parts at least there is a minimum square footage and road frontage required for subdivision of property, often an acre or more property with 100 to 200 foot frontage. What would be tougher to stop would be massive joint ownership schemes where political or special interest groups sell single parcels to say 1,000 people as joint owners. I suppose laws could fix that one too by restricting the extent of joint ownership. The point is that you’d have to very carefully define what constitutes property ownership. Just think in terms of how Wall St.& Big Bank interests quickly finds ways around any new law aiming to reign them in somehow. Political and special interest groups would do the same here.
