I continue to believe that the best way of &#x27;locking&#x27; a price is to ensure that the market remains with the correct supply to buyer ratio.<p>As an example: to decrease the cost of rent in a city, an increase in rent-able locations and attached commercial business and non-retail jobs need to be in those locations.<p>This is also related to suggestions that say controlling medical care could be achieved by allowing more agents at all (doctors or not) to be able to treat obvious conditions.  I agree that in the short term the suggestion would be viable, were it not for regulations; however I think that artificial diagnosis neural networks will probably achieve adoption before the regulations catch up.
