That's the price mechanism controlled free market that we love so much. In a collectible market, the first to market gets the least. The last to sell gets the most. So collectors try to hold on for the very best price. All this collecting does no harm to the economy - though the individual may guess wrongly and suffer.
Land acts like a collectible - and there is the problem.
In the US, the Savings and Loans went chasing after the collectible until the bubble burst. Japan ran the collectible up and up apparently for ever - under forever arrived. They had invested their all in the bubble that is the land collectible. It has become pretty worthless. We have forgotten that.
