If I put a gun to your head, I'm not forcing you to do anything - you can always choose the bullet.

That market economy is running only on voluntary trade is one of the biggest and weirdest misconception that's being spread. Most of the transactions we make are ones we cannot reasonably choose not to make. We can at best choose the vendor we're dealing with.

I think those two things are different despite them both being coercive. Most civilizations have always frowned on the equivalent of holding a gun to someone's head, but not the idea that you need to work to survive.

But let's suppose that force is involved in a market economy. I would agree that it should be there. And its because I'm not from a wealthy background. I've worked with the people that would benefit from this kind of change, and a large majority of them would waste it.
