If your point is that we're likely to explore other revenue models before our current one runs out, then I would absolutely agree with you.
My point is that I'm skeptical of claims that you are creating a bridge to where "we" want to be, if that means a world that does not have trillions of dollars of legacy fiat currency markets that need to be "rippled." By and large the bitcoin community sees no need for a future where a company doing the sorts of things that Ripple does has a central role. That may simple be a lack of vision and the people running Ripple are just smarter than everyone else, or it may be a disagreement as to direction. I suspect the latter.
