Radical innovation is not about making things more efficient, or simpler, or easier, in broad terms. It's about investing in transformative technologies.

I agree with you that radical innovation doesn't come from just making things more efficient/simpler/easier, and I've argued that such a mindset yields local max solutions. The example of Fabricly was only used to display how an approach that addresses the problem from the root and transforms the way an industry operates is what radical innovation is (not about social shopping). Your definition seems to confine it to cutting edge industries with cutting edge technology; however, radical innovation could be in retail/food/other age old industries as much as it could be in space/biotech. Radical innovation is ultimately about the transformative result and technology is only a means to get there.
