that we shouldn’t take dates on the show literally other than as an indication of the general order in which things happened
I absolutely am fine with this take now, especially. Ultimately, what we are talking about is the narrative importance of the events. If we want to have episodes where the characters go to "today" today must continue to exist within the narrative. If the narrative says that the world was noticeably different in 1996 - move it to 2036. If we're still going strong move it to 2056.
These changes don't make as much difference in the narrative that was being told to begin with.
I mean let's be clear for most of Ferengi history women were not allowed to own property of any kind - including clothing and some of their business endeavors include poaching endangered animals and literally being slave traders. I mean - I don't think there's any indication that Ferengi society was anything more than hyper-capitalist dystopia as a juxtaposition of the Federation socialist utopia. That Rom and Quark are goofy and lovable I think speaks more to how bad every other Ferengi is operating outside of a Federation station.
From the Federation's perspective the Ferengi are harmless and in this way they may be ethical enough to not warrant confrontation, but at the same time - the Federation does seem to stop them when they're doing something like slave trading so I think we can imagine that for some people in the sphere of Ferengi influence they're not so ethical.
