If you would like to know something specific, feel free to ask. But seriously dude, i'm not going to write a books worth of text completely explaining my ideas for a new world in a single post, on a forum about virtual dwarves.
That's fine with me; honestly, I thought my (rather rhetorical) questions were specific and intended to point out some of the problems with this sort of idea...some of the reasons why they aren't "as supported as they should be," as you put it. You don't have to address them - I'm certainly not of the mindset of "someone on the Internet is
wrong" as xkcd put it. I almost didn't respond, but since you named me personally (although a lot of my posts were in response to elf-fondling human, as I recall), I didn't want to just leave it like that.
A lot of discussions like this are, shall we say, not very reality-based. It's all very well to say "there's gotta be a better way" but one has to have a plan. One can say "people should be able to work together without violence" but history is full of examples that contradict that theory, so that needs to be addressed.
Ultimately, if one wants to accomplish something, one has to gain power first. Sometimes this takes the form of money. Look at the projects the Gates Foundation is sponsoring, for example. Sometimes it's political power (also closely related to money). Sometimes it's ideological (religion) which, again, gains a lot of power through money. People who have significant money (power), as a general rule, tend not to wish that monetary systems be phased out. Power corrupts and all that. I know a few "flower children" who grew up to become the very sort of "capitalist pigs" that they once demonstrated against.
