 Interlune's terrestrial He-3 extraction program suggests the threat to lunar resource economics may come from improved terrestrial extraction technology rather than just cheaper launch. If cryogenic distillation becomes economical at scale, the scarcity premium driving lunar He-3 prices could collapse before lunar infrastructure is built. This is a supply-side substitution risk, not a launch cost arbitrage.

+EuCo2Al9 ADR materials create a terrestrial alternative to lunar He-3 extraction, demonstrating the substitution risk pattern at the materials level. If rare-earth ADR can achieve qubit-temperature cooling without He-3, it eliminates the quantum computing demand driver for lunar He-3 mining before space infrastructure costs fall enough to make extraction economical. This extends the launch cost paradox from 'cheap launch competes with space resources' to 'terrestrial material substitution races against space infrastructure deployment.'

 WHY ARCHIVED: Nature publication quality + Chinese strategic framing + rapid DARPA response = highest-credibility signal that He-3-free ADR is a real research direction with institutional backing.
 
 EXTRACTION HINT: Lead with the temperature floor uncertainty as the key caveat. The alloy is promising but its deployment-readiness for quantum computing (vs. lab demonstration) depends on the temperature question. Extract as experimental confidence claim pending temperature validation.
