Is it okay for the buyer to lie, but not okay for the seller to ask for the truth and adjust their price accordingly? This 'anything goes' market ideology is the same framework that leads us to deceptive subscription systems, anti patterns etc. Deceiving people to make a buck is shitty behavior.

From an efficiency standpoint it is preferable for a Land Value Tax to incentivize selling to whoever will put the property to best use.

Isn't that true of any price increase due to increased demand? It seems like you're saying a seller shouldn't be allowed to raise their prices as demand increases, because they'd simply be benefiting from a positive externality created by the buyer.
