All citizens share the roadways and mass transportation systems.  Even those who do not use mass transportation can benefit from these services insofar as the systems increase property values by making commuting more efficient.  No individual can have access to such a system without a community or a corporation to provide it.  Since roadways and transportation systems cannot compete with each other, they cannot be operated as efficiently under free market capitalism principles as they could if they could compete.  If the state nationalized the Federal Reserve, it could take back the power to create fiat currency. The state could then use fiat currency to make capital improvements that benefit the public at large.  Injecting money into the economy by paying for infrastructure construction would not result in inflation because the community is enriched insofar as valuable transportation services are provided.
