That's not realistic, you'll always have trade-offs.
Just because something doesn't seem realistic at present doesn't mean we should not prefer it, were it available.
My point is : I do not think bitcoin will be good at handling lots of micro-payments, it is by design. Nor do I desire this capacity. Of course, if someone removes limitations without impacting the core functionality, sure!
But from my experience and the information I gathered from different sources it seems to me that it can't be achieved in such a way, therefore I think micro-payments will be handled by bitcoin banks, not by the block chain. And from my experience, this position seems to be a consensus amongst the bitcoin community.
