My cents -
For those of you lost in the question of how money can be lived without, that is a perfect answer for a capitalist. You are a capatilist, almost by blood.
You have alot to read about in anarchism, marxism, and other alternatives.
Granted money itself - not a problem. People create ideals and ideologies around money which bring it to an evil; greed.
This is one of the most complex topics you can think of, it is the drive for all of us, yet it is made by us, it is not a mineral, it is not a food, it is not any source of energy - it is a symbol, yet we all want it and we all need it to live (especially if we're browsing a forum).
To say it could be discontinued is a bit premature in your knowledge, but to say that money is an absolute necessity, you are to a point of being blinded. There are very basic concepts that need to be put in place where money will no longer cause such evil - but they are too basic to be studied, and too basic for the 21st century to uphold.
If I told you that you had to live in downtown to work in down town, you would probably get angry with me, say its not possible, say it's too expensive, or a number of other things. At that point I would tell you not to live in downtown, and get a new job closer to where you live - you would say it doesn't pay enough, and it doesn't accomodate your needs. The problem is not the money, but the ideology in which you live.
It is not OK to drive to work every day
It is not OK to work from dawn until dusk
It is not OK for prices near your work to be higher than your wages
It is not OK to have your work not fit your interests, or if they don't you need to be compensated.
What has happened is a hurling over of ideas that were not OK, but nobody at the time saw the problem. The free way is an ideological monster, a hidden domination over us all - it is paid for by you at some point, but facilitates movement from the inner city to the outer, where your job and your house are respectively. Yet you cannot live in a big city - the crime, the pollution, the noise. All of these are by products of the early onset of mega-capitalism, mega-consumerism, and in fact, ALL stem from the highway and freeway system itself.
What you are all argueing over is not the same thing, and argueably none of it is created by money. You should take your discussion to the ideological advancement of consumerism, post-consumerism, capitalism, international trade, internation corporations, owners and CEO's, interest in banks, debt, and beyond. Getting rid of the paper that institutes it all will just make the beast angry.
