Con-D.2.7 --- Garbage-Collection Analogy Backfires: Modern GC Moved Away from Stop-the-World
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*Severity: D (Substantial)*  |  *Sphere: Se1, Se6*  |  *Target: ax25*

Reply 1b's efficiency argument for periodic over continuous
redistribution uses the analogy of stop-the-world garbage collection
(periodic Jubilee) vs. real-time garbage collection (continuous
taxation), claiming periodic GC has lower amortized cost. **Taken
seriously, this analogy argues against a Jubilee system:**

1. **Stop-the-world GC is universally recognized as inferior for most
   applications.** The JVM abandoned pure stop-the-world GC in favor of
   concurrent collectors (CMS, G1, ZGC, Shenandoah) precisely because
   stopping the world creates unacceptable latency spikes. Modern GC
   research focuses entirely on *minimizing* stop-the-world pauses.

2. **The correct analogy for modern GC is progressive taxation.** Modern
   generational GC distinguishes between short-lived objects (collected
   frequently, cheaply) and long-lived objects (collected rarely,
   expensively) --- precisely the structure of progressive taxation.

3. **Anticipation effects destroy the Jubilee mechanism.** Economic
   agents have agency (ax15!) unlike software objects. Rational agents
   anticipating a Jubilee will convert resetable assets to non-resetable
   forms, move wealth offshore, consume capital, under-invest before and
   over-invest after the reset. This is the **Lucas critique** (1976):
   agents' behavior changes in response to announced policy, potentially
   rendering it ineffective or counterproductive.

4. **The "constant balancing" overhead argument is empirically wrong.**
   Countries with strong continuous redistribution (Denmark, Sweden,
   Norway) have *simpler* regulatory frameworks than countries with weak
   redistribution (US). The US's complex regulatory apparatus is a
   product of *inadequate* redistribution, not excessive redistribution
   (Kleven 2014).
