the whole point of a free market place is that people buy and sell things of their own freewill.
There is nothing free about market places.
They only really involve freewill if what you are buying are things you don't need. Its an easy mistake to make, when you are well off and in a land of plenty
Food, for instance, is not something a person can go out with. If I produce food, I will need to defend it, either with personal physical force, or the vicarious force supplied by the government/police, who will demand taxes. If I don't produce it, but decide to take it, I will need to use some kind of force. On a basic level I can do this with either personal physical force, or by refusing to give something that someone else needs to them, unless they give me food. Bartering then becomes a basis for a monetary system.
'Fair price' depends on enforcing bargains. And people will invariably do what ever they can do to get around this enforcement. You cannot have a market without security, without punishment for those who do not want to play that game. Its only free if I have the option not to pay.
Trade is polite, even civilized, but generally only when there is plenty to buy, money to buy it, and punishment for those who don't play ball. Its like gladiators in an arena, its formalized warfare, as opposed to getting knifed in an alley. I'd rather be a gladiator, but I wouldn't want to be one.
competition will drive prices down but not below the minimum that people are willing to work for.
I'm a big fan of capitalism, it works very well in modern society, but I think you are being naive. Take away our technology and we would return to serfdom and slavery in two shakes of stick. Without our machine slaves, we would need animals... and other humans to do our dirty work.
the existence of any coercion or intimidation would completely eliminate the whole concept of a 'free' market place and therefore 'fair' market prices.
No one wants to pay for things they don't have to, and most will turn a blind eye, if they think they can get away with either getting something free or increasing profit, increasing profit means money to buy other things we can't get for free. Money is a great way of coercing people to do things they would never normally choose to do.
if prices are fair and non-arbitrary then morality can be also.
They aren't, and it isn't. Pretending otherwise may make it easier for you to sleep at night, but its not reality, which can be wonderful and horrible. Simple moralities are based on an emotional response...hot->pain->bad->thou shalt not... of course as long as the pain isn't our own, we can think of all kinds of 'greater and lesser evils'. And what we can't see, is easily ignored.
