A town council has decided to close a local library due to budget constraints, despite protests from residents. The council argues that most people now access information online and that the money saved can be redirected to essential services like social care. However, community members point out that the library serves elderly residents who are not comfortable with technology, provides a warm space for homeless people, and offers free activities for children whose families cannot afford other entertainment. A community resource should not be judged solely on how many people use it, but on how important it is to those who depend on it most. Services that protect the most vulnerable members of society should be the last to be cut, not the first. Which one of the following illustrates the principle used in the above argument?
