Star Trek Paradigm: humans are limitlessly ingenious, technological solutions will save us, and Nature is viewed with an anthropocentric utilitarian ethic.

That's not Star Trek at all! The United Earth Government already abolished currency and converted to a socialist mode of production before the replicator was invented. More technology doesn't necessarily help. When 21st century Earth got more technology, they used it to do the Eugenics Wars and WWIII. Replicators haven't helped the Cardassians, the Ferengi, the Romulans, or the Klingons with solving poverty, pollution, scarcity, or slavery. The reason Earth has solved those problems and its technological peers have not is that Earth is more socially advanced. Humans do not use money. They work to better themselves and their species. Picard's family makes wine on a vineyard. Sisko's dad runs a creole restaurant. Earth is the picture of human harmony with both society and with nature. Most humans have never even eaten a dead animal anymore.

Plus, Starfleet exists to explore the infinite diversity of nature and of society out in space. Starfleet is full of biologists who love exploring strange new worlds. The sovereignty of indigenous life is respected, so much so that it is called the Prime Directive.
