This is not about Picard, it is about politics. Left-winger embrace the economic vision of Trek while right-wingers detest it.
But the opposite would be true too, one side would support the observed economic system that obviously employs a form of money, while the other side would "detest" (or something milder) the very idea that centuries from now a financial system that is similar to our current one is still in existence.
And it isn't simply about politics, it's also about sociology. The structure of the future. The economic system that our see heroes live in, is the one that we want
to see them living in. Many Star Trek fans project themselves to a degree into the Trek universe, we envision (fantasize) ourselves in that universe. So in discussions when we advocate a economic system, or a type of interstellar culture, or a Federation legal structure, or tremendous diversity, or high degree of uniformity, it's because that's basically either what we personally would like to live in, or at least what we would like to see our heroes live in.
