 However, even if the Generalization Argument, as stated, is unsound, perhaps it is on to something. There are certain classes of actions in which we tend to presume everyone ought to participate (or ought not to participate). For instance, suppose a university places a sign saying, “Keep off the newly planted grass.” It’s not as though the grass will die if one person walks on it once. If I were allowed to walk on it at will while the rest of you refrained from doing so, the grass would probably be fine. Still, it would seem unfair if the university allowed me to walk on the grass at will but forbade everyone else from doing so. It seems more appropriate to impose the duty to keep off the lawn equally on everyone. Similarly, if the government wants to raise money to provide a public good, it could just tax a randomly chosen minority of the citizens. However, it seems more fair or just for everyone (at least above a certain income threshold) to pay some taxes, to share in the burden of providing police protection.
