I'm not sure a permanent devaluation will ever happen in housing, it seems like one of those types of markets in which there is a definitely finite supply and as a result there will always be sufficient scarcity to drive up demand and consequently price most people out in the longer term, monopoly only ever gets played one way, international competition/globalization I think only ever posed a temporary break on that tendency (in other markets too).
I do think there's a moral and economic case for the taxation of supernormal profits and especially where rent seeking is very definitely a market failing on transfers and transactions.
This is part of the tendency to exclude all but a precious few from the status of ownership. Marx analysed it a long time ago and I cant say he was wrong about, it also was not much of a fresh insight, even then, and had been detected by a lot of earlier economists.
Unfortunately, because it was Marx, and because of the associations with socialism or communism, anathemas to the American mind, it cant be admitted into US consciousness, unless its qualified by anti-semitism or sectarianism or racism.
It can be admitted if it validates WASPs persecution complexes, not if its a basic rule of the economy because WASPs are meant to love the economy and resist any interference with it at all costs.
