There's no "free-ish" markets. There are free markets, and there are coercive markets. If someone is forced to toil or purchase something against their will, that's not a free market any more. If your argument is that free markets can't survive the influx of assholes, then argue that, and we'll have a discussion about how to keep assholes out of free markets.
Of course there are free-ish markets.
I don't see how reality is anything near this black and white.
So what's your definition of free market anyway? What aspects do you consider coercive? Regulations? Laws?
I have been arguing that when you start out with a free market that is not protected by some statist structure the assholes will win quicker. Assholes will be there, free market or not. It's just that a free market offers more opportunity to being played with. When the ante is small, that's ok. But when the ante is your livelyhood or your house, not so ok.
You will need some way to prevent monopolies without coercion. Monopolies completely destroy the idea of a free market. For a lot of things someone is going to be top dog because being a little better can get you all of the business. Not just because they are assholes, but because it is how the game of free markets is played. Monopolies give power and that will invariably get abused.
Historically, the assholes always got more free reign in centrally controlled economies.
ZeitG is an example of a centrally controlled economy, and any implementation of it would result in massive levels of coercion.
Read "The Machinery of Freedom". There are ways to ensure some degree of justice, and have protection from coercion without statist structures.
