But in the more extreme,
truly public cases, the free-rider myth is even weaker. That is because the free-riders, in cases like defense or transit easements or other like situations
impose no significant cost. The example of a lighthouse is a good one. An entity operating even a tiny number of valuable ships in a coastal area will realize benefits (their ships not sinking) on building a lighthouse themselves, regardless who else sees the light and navigates by it. The provider is made no worse off by those other eyeballs -- and, most important,
the lighthouse gets built.
