Money
Money's accessibility follows a deeply inequitable distribution. Roughly half of the world's wealth belongs to approximately one percent of its population. For billions, money remains perpetually insufficient, always needed, never quite obtained. Yet paradoxically, nearly everyone possesses some money. The concept requires no special abilities to grasp, no unique circumstances to encounter. Even the poorest child understands that coins acquire sweets. The barrier to entry is low; the barrier to sufficiency remains insurmountably high for many.
Wonder Woman
Accessing Wonder Woman's assistance presents considerable logistical challenges. One cannot simply ring Themyscira and request an appointment. Her attention focuses primarily upon extinction-level threats and matters of cosmic significance. The average citizen facing mundane difficulties - a leaking roof, an unfair dismissal, a problematic neighbour - cannot reasonably expect Amazonian intervention. She exists in a realm removed from ordinary concerns, magnificent but distant. This inaccessibility, whilst understandable given her responsibilities, limits her practical utility for most humans.
