Silly nitpick but the free market absolutely can, and has in the past, put a monetary (positive)value on your person.

We have of course abolished slavery since then.

Which is a weird way of saying I don't think we necessarily should put a monetary value to people. Instead we need to realize that money isn't everything in life. So much of life is unpriceable, and that's as it should be. Attempting to price the unpriceable necessarily makes a mockery of the unpriceable thing.

You guys have to look up where the concept of Dignity came from.
