Well, if that is the case, the free market is a pureley theoretical concept, that is not realized anywhere in the world. And it cannot be realized, because there is always inevitable some form of information assymetry.

Something can be a theoretical concept and still useful. For politics you might want to favour transparency instead of obscurity.

As an employee in software I've been working through intermediaries for a good part of my career, so obviously interested.

I suspect that, at least in my country, it's more a matter of bad regulation than of information assymetry. But the mere fact that we're not sure which are the causes is in itself information assymetry.

economics 101 right here. free market is a theoretical model.

Since there is inevitably going to be information asymmetry, this is rather a "no true scotsman" approach to redirecting blame away for the problems that plague free markets in the real world.

"I support our free market! But since our free market isn't really a free market, I'm still right and it's not my fault if things go wrong!"
