In societies outside the Federation, where they don't have replicators, things have value due to being able to use them for other purposes. Latinum has never been shown to be used for any other purpose except to trade. Its not clear why a useless material is considered valuable, except for the fact that its rare.
Yes, but beyond its scarcity, what other purpose does it have? Lots of things are rare and can't be replicated, but their value comes from the need to use them for some purpose such the ability to build other things that you wouldn't be able to build otherwise. Latinum has never been shown as anything more than a currency with nothing behind it to give it value.
Define "post-scarcity". You can't replicate everything (without programmable matter, anyways...), and some raw materials are needed to build the replicators. And latinum is a rare commodity, though I don't know why it's so value beyond its scarcity. Greed will always be there as long as some things remain scarce yet required for a functioning society.
It's not even really a swear word. Slightly vulgar, maybe, but "pussy" isn't on the same level as "fuck" or "shit". It's not even the same level as "bitch" or "turd". Ironic...the site was built by pussies...
The "General" part doesn't really count since all Jedi were automatically commissioned with high ranks during the war. Ahsoka was a Commander at 16, leading troops into battle while still a padawan.
