Each time an intervention occurs, it distorts demand. If the distortions aren't allowed to recede, further interventions that supply "easy money" will exacerbate the problem until it is no longer possible to compensate and the money supply is so far removed from real demand that bubbles form (demand that responds to the increases in money supply as opposed to real assets and productivity).

What I've described goes beyond simply making trade easier and crosses into the limitations of human perception on grand scales. Trade only gets so easy - the excess doesn't help. Because Alt/Bitcoin manage themselves internally, these distortions are virtually impossible. When distortions begin to occur, the system self-corrects. I'm sure there will eventually be certain specific situations where complications could arise, but for now they are two sides of an extremely sublime system
