Have to agree - it's this utopia and humanity's optimism that got me to watch Trek in the first place. I mean, if I wanted grimdark and a more gritty setting where humans behave like humans do today, then I watch Star Wars. Which I do too, depending on the mood. This way, all the franchises can offer me something unique.
And I don't think Roddenberry "fethed up" Trek. Most of what you, Amaya, label as inconsistencies can easily be explained by pointing to the "try to be good" schpiel I mentioned in my last post.
Let's touch upon the issues you mentioned as examples of how I mean this:
There have been human societies that existed without money (or still do), simply based on the concept of unity and mutual cooperation. It's the communist ideal, and if a society actually manages to instill such selflessness in its members that they can resist the corrupting lure of greed, then it can work out. Especially if said society has access to technology that is capable of covering everyone's basic needs and let people live in paradise.
Yes, money is not inherently evil, it's just a gateway drug to power, corruption and abuse. Blame humanity for being so vulnerable.
"The Federation can't cloak" was a political deal intended to diffuse the tension amongst the Romulan Neutral Zone and end/prevent an unnecessary war triggered by nothing than one side's paranoia. The Romulans regarded this tech as an important advantage, and the Federation was okay with letting them think they keep the upper hand by this if it means that they don't see the UFP as an aggressor.
Lastly, "no Starfleet officers would go rogue" is
BS. This was a topic that was already touched upon in
TOS, and multiple times at that.
It even ties in with the "Federation can't cloak" deal in that a part of Starfleet secretly and illegally developed an advanced cloaking/phasing device with the so-called Pegasus-incident in TNG - and Roddenberry still had a say in matters at that point in time.
No, personally, I actually think that Trek was "fethed up" as Roddenberry lost influence, and some people decided to start pandering to different audiences. As much as I like the DS9 Dominion War episodes, they are not really Trek but more like Star Wars, focusing on lots of explosions and spaceships that suddenly behave like starfighters, dodging lasers and blowing gak up. No wonder this culminated in "Lensflare Trek", and I'm actually somewhat surprised they didn't get Michael Bay rather than
JJ for the new movies.
