I have a feeling some of this might strike some anons as odd, and probably quite fanciful, but what the hell, here goes:
>No nignogs, pakis, or chinks (Japs are fine); trannies are also verboten, for obvious reasons
>Government is an aristocratic republic where the senate is limited to shareholders and landowners in the community, sort of like the Roman republic
>Economic focus on tech in all its forms, from privacy technology and arms manufacture to robowaifus and virtual reality; this forms a crucial part of the community's economy, esp. exports
>Imports are primarily food, drink, raw materials, etc.
>Cryptocurrency is the standard currency, though others are accepted for inter-personal transactions; no currency is expressly illegal in itself
>Military is primarily a mixture of standing militias (compulsory membership), with PMCs occasionally assisting with training
>Community is walled on all sides by various anti-intruder detection/incapacitation mechanisms (electric fence mazes, minefields, etc.), like a modern-day castle town on steroids
>Death penalty is legal for child molestation, first-degree murder, premeditated arson, and gratuitous animal torture
>Profession of socialism in any capacity whatsoever is an exilable offense; this does not extend to voluntary insurance plans such as tontine, etc.
>Mostly laissez-faire on private life, though possession of hard drugs (i.e., not including alcohol, marijuana, psychedelics) is an exilable offense due to the potential of certain drugs to incite homicide and property destruction
>In-utero gene-editing is legal, esp. for all babies with serious congenital defects
>Has a strict policy of shooting all trespassers dead (if they make it through the perimeter defenses)
>Citizens who wish to leave may do so at their own discretion, though if the move is permanent they have to forfeit citizenship
>Instead of state welfare, the recently-unemployed are invited to join the militia if they can't find a job in their field
>The basic requirements for immigration, other than the aforementioned racial component, are a clean criminal record (as judged by the community's standards) and a competitive skillset in tech and/or military endeavours.
>Emphasis on harmonizing architecture with greenspace; modernist architecture is outlawed because it's fucking ugly
TL;DR, a techno-libertarian castle fortress based on the Roman republic and populated entirely by whites and Japanese. And waifubots.
