> Tens of thousands of attempts to implement Marxism, with a 100% failure rate.
Ten thousand attempts but you didn't seem to feel that the specifics of a single one would illustrate your point? It doesn't seem to me like you're making an evidentiary claim, it seems like an ideological one. And that's not an invalid thing to do but I do think we're increasingly debating politics and ideology and not discussing critical thinking.
The closest you come to a specific example is here:
> Did you know that the US has had over 20,000 communes tried? With a 100% failure rate.
But come on, you must know that there are communes which are successful (eg Israel is well known for it's kibutzes, which are their mode of commune) and that Marxists don't have a monopoly on the concept of a commune. Eg, libertarian seasteading (which also has a rough track record) is a similar concept, but libertarians are seldom Marxists. Intentional communities usually fail, for more or less the same reason startups usually fail; it's a difficult, risky endeavor.

To be completely honest, it seems to me like "Marxist" to you means, "someone who is young, politically left of center, and who's ideas I disagree with." Frankly I don't think you have a good grasp on what Marxism is? You're mostly using generalities and when you do get specific, it's usually weird stuff like "the crew of the Enterprise are loyal and selfless" that's entirely tangential. (The notable exception being where you mentioned Marx's prediction that capitalism would implode.)
The Hollywood stuff is really reaching. Star Trek is utopian, but utopianism isn't Marxism, and the Ferengi aren't the villains (except in a handful of TNG episodes and one Voyager episode - and I haven't watched the newer stuff like Picard, so perhaps I'm missing some here and there). They're mostly in Deep Space Nine (where they're in nearly every episode), where they are protagonists. The workers do not own the means of production in Star Trek, there is no class struggle, there's nothing about historical materialism, there's nothing I can think of (also a lifelong Trekkie) remotely Marxist about it.
If you lump Communism together with Marxism (they're not identical concepts but they're close enough, sure), and take the definition of Communism as "a stateless, classless, moneyless society where workers own the means of production," then there are some surface level similarities. The Federation is moneyless, and while they aren't classless (they're a meritocracy, so class still exists), they are egalitarian. That's pretty thin as far as it being Marxist or Communist. It's techno-utopianism, something I'd associate more with Libertarianism (in that I mostly hear it from people of that persuasion, eg Elon Musk [an avowed anti-Marxist], though I wouldn't call Star Trek Libertarian either).
To respond more specifically:
> The Enterprise is the perfect Marxist society, presided over by the incorruptible benevolent dictator. His loyal comrades are all selfless, also incorruptible, and utterly lack any ambition whatsoever other than serving the ship. Everyone selflessly shares equally. There's no money, and no crime.
None of these things are related to Marxism (except money as discussed earlier), and there's tons of episodes about flaws in their society or crimes that happen. You're objecting to utopianism.
> The bad guys, the Ferengi, are (naturally) capitalists, with their ugly faces and pointed teeth. They are always wrong about everything.
They're regularly the heroes of the story in DS9, where their negotiating skill or enlightened self interest saves the day. (An arbitrary example from the top of my mind: https://www.youtube.com/watch?v=hdQcGzbpN7s - in which the Ferengi Quark convinces someone to pursue diplomacy over violence because the "price of peace" is at all at time low)
