Trek has no money in the Federation; no barter. Nobody who's watched a season of any Trek show can avoid noticing that. It might be a bit murky with characters like Harry Mudd, or the Ferengi, but those operate outside the Federation; you'd have to be daft to miss that. TNG was more careful with their "capitalist" characters like Kivas Fajo, who was clearly a collector and trader rather than a travelling salesman.

Right-wing free-market Trekkies are self-deluding.
