What constant launch cadence is implied for moving components over 100 years?
Launching hundreds of fully-loaded Saturn V rockets every single day for a century
To estimate the transport effort necessary for building a structure of the Death Star's magnitude, assuming a constant shipment rate from Earth over a century provides a dramatic illustration of the logistics involved. If calculating the required material shipment rate to be $10^{10}$ tons annually, this translates to an extremely high launch frequency. This frequency is equivalent to launching a massive vehicle like a fully-loaded Saturn V rocket hundreds of times daily, every single day, without interruption for 100 years, just to move the raw structural materials, not accounting for the mass of fuel, construction machinery, or personnel transport.
