It helps demonstrate where additional investment and development might be warranted. If we have hit a physical limit in networking, then that is one thing - but if we are only hitting an artificial limit because our technology and infrastructure is not sufficiently advanced - then this problem is actually showing an opportunity. As an architect you have to sometimes ignore constraints to understand if the final picture you would assemble makes any sense. If the final picture you assemble makes sense, then working backwards through the limitations, to find out, are these really limitations or are these opportunities to innovate? That's my thought as to why you would imagine they are not a limitation. To aid in brainstorming, innovation and identify opportunities for improvement, or alternative solutions you would not have seen if you simply accept the bottleneck as a given.
