Oh. It takes money to do that? Well shoot.
EDIT: to actually respond to the video clip, it's kind of surprising how interesting Star Trek got when they threw out some of Roddenberry's ideas during the Deep Space 9 era. The Starfleet people co-existed with the Ferengi and Bajorans who didn't have post-scarcity economies. The Bajorans were also highly religious. Starfleet had a shadowy spy organization willing to assassinate foreign leaders. A Starfleet Captain becomes a traitor to Earth-- twice!
And yet despite that, Deep Space 9 is one of the most beloved Star Trek series.

(Quark is selling an auction of a 1950s baseball card Jake wants. Jake's convincing Nog, a Ferengi, to help him.)
Nog: "It's my money, Jake! If you want to bid at the auction, use your own money."
Jake: "I'm Human, I don't have any money."
Nog: "It's not my fault that your species decided to abandon currency-based economics in favor of some philosophy of self-enhancement."
Jake: "Hey, watch it. There's nothing wrong with our philosophy. We work to better ourselves and the rest of Humanity."
Nog: "What does that mean exactly?"
Jake: "It means... it means we don't need money!"
Nog: "Well, if you don't need money, then you certainly don't need mine!"
