I mean the similarity is not a coincidence. Gaming chairs are modeled after racing seats which are five point harnesses designed to keep the occupant safe in a car crash… exactly like toddler car seats.
I can see a use for actual racing seats in racing games to enhance the immersion. The faux racing gaming chairs took off because some chair company sponsored streamers. Streamers like them because they’re something to look at on stream rather than a bland office chair. For everyone else a bland office chair is way better.
On a technical level, federation is arguably just as compatible with libertarianism. Each instance is its own island nation, free to set its own rules while members vote with their feet in free association. That it hasn’t gone that route is more to do with the founding population than the technology.
