b/c the congestion really has only just begun. if it persists, yes, ppl will start to stop using Bitcoin. the exit starts slowly at first and then will morph into a stampede; especially if the price starts plunging. the mempool is a problem that does have to be fixed so that ordinary users can start getting their tx's through. they won't be as patient as some of us here.
