Not sure if this is the right spot for this question but, I was working some fan fiction centered around one of my STO toons. Part of the story takes place on Earth. And I suddenly was struck by the idea that not only "how" but "why" would anyone go out to eat, or go window shopping, or look for collectibles in a society where money doesn't exist?
With replicators all over the place, who would go to a fancy restaurant for a good meal?
With out money, why would you go looking for souvenirs or collectibles to buy? In fact, why would anyone sell collectibles or souvenirs?
Many of what we look at today as enjoyable activities today would be gone in a world where money didn't matter. Granted, you could probably come up with other activities but many of those that take us out and about among other people would be gone.
This makes some scenes I've seen in TNG and other versions of Star Trek questionable.
