Of course you're right that everything starts with the first step, but it increasingly seems that we're averse to even taking that step. And I'd also argue that the dramatic differences in economic and technological 'power' available today also must change what is considered a large scale. Skyscrapers, for one example, were once a visionary undertaking but have long since become completely mundane construction/engineering projects. The Line was designed to be literally modular, being made up of 135 modules of less than a km in length each. That such a "vision" is considered exceptional, to the point of even not being realistic, is something that to me feels like a complete deterioration of the vision and ambition in society.
