Pizza
Access to pizza has never been more democratised. In major metropolitan areas, pizza can be summoned to one's location within 30 minutes via mobile application. Frozen varieties await in supermarket freezers. The ingredients for home preparation are available in any grocery establishment. Price points range from budget-conscious to extravagantly premium, ensuring pizza remains accessible across economic strata. Physical proximity to pizza, for most of the developed world, measures in minutes rather than miles. It is, quite simply, there when you need it.
The Moon
The Moon presents what physicists might charitably term an accessibility challenge. Located 384,400 kilometres from Earth's surface, it has been visited by precisely 12 human beings in the entirety of history, all of them American astronauts between 1969 and 1972. The cost of lunar access currently exceeds the GDP of most nations. For the overwhelming majority of humanity, the Moon will remain forever visible yet utterly unreachable, a cosmic tease hanging in the night sky. One can look, but one cannot touch, taste, or otherwise engage.
