Clearly, a government that ignored this principle, seeking to eliminate the very actions and goals that we regard as desirable, would hardly be conducive to a smoothly functioning society. By "legal" we mean legally allowed, i. e., permissible under the law. Suppose, for example, that there are two kinds of fruits on Crusoe's island, one of which is very nutritious, while the other constitutes junk food. If both kinds are palatable and easily available, and assuming that either fruit can be picked without aggressing against others, then clearly it is in Crusoe's self-interest to eat the more nutritious fruit, and we can assume that this is the moral action X. If other people on the island form a government, then the Ethical Consistency Principle requires that they not interfere with action X.
