Trekkies
The default unit of the Trekkie phyle is the spacecraft. Several hundred is an average crew, organized as meritocratic-ish dictatorships based around military discipline controlling access to the fabricators through passwords and biometrics. Essentially, an 'ensign' has only limited quantity of mass they can access to fabricate and limitations like 'can't make weaponry without the approval of the tactical officer, can't make drugs without the approval of the chief medical officer, can't change the ship's course without the approval of the navigator, etc.' The duty of Ranking Officers is to distribute resources and if the Enlisted Officers are dissatisfied with their choices and/or request it, 'put them ashore' at a convenient source of raw materials such as an asteroid or failed earlier space colony with no survivors with an unrestricted fabricator to create their own ship, aboard which, they will be the Ranking Officers. Ranking Officers must balance keeping their crews satisfied so that the crews don't leave and maintaining enough of a meritocracy that all the vital equipment for keeping humans alive in space is maintained and competently operated. Failures tend to either lead to everyone dying or a captain seizing totalitarian power or 'being promoted to the admiralty' as the trekkie slang goes. The phyle as a whole attempts to ideologically excommunicate said admirals as traitors and a black mark against themselves, but has little success in doing so since MAD deterrence applies to close-range ship combat and nothing else can reach a ship, so there's nothing stopping the admiral from simply ignoring their demands and continuing while they spam the Nets with 'but that guy isn't a real trekkie'.

Grounded/Based Trekkies
A subphyle descended from the result of a group of trekkies 'put ashore' at Iapetus who rather than doing the conventional trekkie thing of building a magnetically accelerated Verne Gun to launch a sufficient mass of iapetusian raw materials into orbit to build a new ship, created an immobile artificial habitat governed equivalently to a ship, save that 'being put ashore' means being supplied with life-support-equipped ATVs/rovers and an unrestricted fabricator and driven around a hundred kilometers away from the nearest habitat to build their own. Assuming the current rate of habitat creation vs failure, it is estimated that in approximately two centuries, the current status quo of maintaining hundred-kilometer demilitarized zones between habitats will cease to be practical on account of Iapetus being too small, at which point either the iapetusians will somehow form a lasting peaceful alliance, have a war between habitats and Mutually Destroy themselves, or return to a more conventional trekkie ship-based nomadic lifestyle.
Interstellar Trekkies
Ideologically, the trekkies are all for spreading beyond the solar system, but practicality has limited them since without a source of raw materials a matter of years away at most to 'put people ashore' at and defuse tensions, they'd have no means of settling onboard dissidence aboard an interstellar generation ship. Several ships have tried anyway, but none have arrived at their destinations yet and with the loss of communications with sol-based civilization, nobody but their own crews can tell if they've been able to avoid Admiralty dictatorship and/or mutiny and everyone dying. One stratagy proposed on popular trekkie messageboards would be to take a small moon, large enough that it'd take generations for a single starting Iapetus-style 'starbase' habitat to replicate to fill it, during which, hopefully, it could reach its destination and build an absolutely immense orion drive engine capable of moving the whole thing, but nobody's actually tried it yet.
