It seems a bit premature to judge that way. For example now that the exchange rate is slowly falling, more people might be considering to part ways with their BTC. So things might eventually settle down. It is still very early days. Also, I suspect few people realize that they should not hold on to their normal money because governments will continually seek to devalue it (that seems to be the takeaway from the article, that that is the normal procedure for "normal" currencies). Their spending habits are probably more governed by their prospects to earn money in the future, or their savings, rather than a look at the value of their money.
