> none of this will matter anyway That's a bit of a self-fulfilling prophecy. What I mean is that the mindset that "none of this will matter anyway if <foo>" injects some measure of irrational optimism into the economy, causing the relative economic severity of the occasional inevitable blip to increase somewhat. We'd all do well to rationally consider the (small) risk of widespread destabilization. Doing so may keep bubbles smaller, but that's a good thing insofar as they are bubbles relative to value.
