The government builds new roads to lower transportation costs.
NASA spent a less than 1 shuttle mission worth of funding to research scram jets over 7 years. Resulting in the X-43 which hit Mach 9.68 using an air breathing engine. , NASA Dryden engineers said that they expected all of their efforts to culminate in the production of a two-stage-to-orbit crewed Vehicle in about 20 years. However, the program was canceled, so, in the end you could be right
Still, scramjet's are one of the few technology's to be able to reduce the cost to orbit to 1/10th - 1/100th of current costs and instead people want to wast billions trying to build a moon base?
PS: The whole point of infrastructure is to lower prices. People could drive across the country before the interstate system, but it suddenly became cheaper and faster in large part because you could avoid stoplights and pedestrians etc.
