Dear Dareal Noxim,
We have transferred the tax.
We expect to have reached around peak production of superstructure components, unless additional factions wish to deploy Quintessence Field Projectors. The Astai Republic itself has nearly deployed megadomes on all planets, after which we may switch to deploying our own Quintessence Field Projectors.
We expect a reasonable upper bound of another 500 rare elements in the next 50

, though this is no guarantee because it depends on market conditions.
Sincerely,
Al Guidicianni
