 When a lot of people think about markets, what they have in mind are multinational corporations, enormous investment banks, Wall Street, these institutions that shuffle huge sums of money around the world. And those things are certainly part of markets, and they emerge on top of markets. But when libertarians talk about markets, when we say we defend free markets, we have something far simpler in mind. So if you have a society where people are free, where they have the freedom to make their own choices about their own lives, and you have a system of property rights, so I can be sure that what's mine is mine, and what's yours is yours, then we can encourage exchange. And exchange is when I see that you've got something that I would like, and I've got something that you would like, and we say, you know what, I think both of us would be better off if we swapped these. We can contrast this with the other ways that I could go about getting something that you have that I would like, which would be I could steal it from you. I could get someone else to steal it from you. I could defraud you by saying, look, I'm going to give you this thing that is super valuable, but it's really not, and get the thing from you. But in a market exchange, in a free, uncoerced exchange, we both go into it knowing what we're going to get, and we both come out of it happier than we were before. And that's what libertarians mean by markets, is that simple, active exchange that when aggregated over and over again forms the basis of the economy, forms the system that makes us all so much wealthier, so much happier, so much healthier. And so it's that simple, active exchange, uncoerced, multiplied over and over again, that libertarians mean by markets.
