Develop the reciprocity-dissolution argument in Chapter 12

What

Chapter 12 (WIP) addresses philosophical foundations of UBI. The book's most original philosophical move — that reciprocity concerns dissolve in post-scarcity because demanding human labour when machines produce is logically incoherent — needs full development here.

Why

The counterargument audit identified that the free-rider objection is currently addressed superficially ("taxed back at the top"). The book's actual position is far more radical: in abundance, the concept of free-riding becomes meaningless. You can't free-ride on machine production any more than you free-ride on sunlight. This argument needs explicit philosophical development.

How

In Chapter 12's section on justice frameworks, develop the argument through three moves: (1) reciprocity assumes scarcity — it governs how finite resources get shared among contributors; (2) when production doesn't require human input, demanding contribution as condition of access becomes arbitrary gatekeeping, not justice; (3) the burden of proof inverts — in abundance, you must justify EXCLUDING someone, not justify INCLUDING them. This connects to the post-scarcity concept page and the broader argument about consciousness shifts.

Impact

Fills Chapter 12's most significant gap. Provides the philosophical foundation for the book's distinctive position that UBI becomes an access right rather than a welfare payment.
