No, not at all.  

XRP is not an IOU….with Ripple, instead of your IOU's being trapped and controlled by a central entity, you can move them freely…In Ripple, an IOU is not a means by which you can buy something now, and pay later.  It's a representation of actual assets you own. When you exchange those IOU's, the asset balance is transferred to the new owner.  The IOU simply determines who now owns that balance.
