> For housing, from the house seller's point of view, they could have the viewpoint that there are far too many houses for sale, the supply is too high, they want a higher price for their house. And from the buyer's point of view, there aren't enough houses because they want to pay a lower price.

And who is right is then determined by the market, because "not enough" means "the price is higher than the cost of creating more" at which point the market creates more. Unless the government is suppressing the ordinary market through rules imposing artificial scarcity, which is the evil to be prevented.
