Pro-E.2.11 --- Response to Con-E.2.11 (Arrow's Impossibility)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*Impact: E (Moderate) --- Resolved.*

Arrow's theorem proves that *perfect* aggregation is impossible ---
not that democratic governance is impossible. Every functioning
democracy operates within Arrow's constraints by relaxing one or
more conditions. Electoral systems work by restricting the domain,
accepting non-IIA, or accepting strategic manipulation as a cost.

**Jubilee design would similarly operate within Arrow's constraints:**
The "first will be last and the last will be first" principle
describes a 2-leg Jubilee cycle. In Jubilee round 1, some parties
are winners and others losers (Arrow's theorem guarantees this). In
Jubilee round 2, this is remembered and corrected. As long as the
*compounding* of inequalities is prevented across Jubilee cycles,
maintaining a somewhat level playing field becomes more manageable
than achieving perfect equality in any single round.

The institutional design questions (which assets, what thresholds,
to whom, what exceptions) are real and important. Finding gentle,
kind, reasonable answers requires scaling up a ResearchCity.
Arrow's theorem constrains the design space; it does not empty it.

**Why Impact E:** The objection is fully resolved at the logical
level: Arrow constrains but does not prohibit workable Jubilee
design, just as it constrains but does not prohibit workable
democracy. The 2-leg correction cycle is a genuine structural
response to Arrow's cycling problem.
