I am not familiar with the intricacies of Swedish “markets”, nor familiar with a common prescription or enforcement thereof. But let me set you straight on the presumptive correlation between a “free-market” vis-a-vis an “unregulated market”.
First, no unregulated market is actually free, for the simple reason that freedom cannot exist without its paradox. The pursuit of individual freedom requires paradoxical rules to protect the interests of collective freedom, as the basis for trust instilled in the marketplace.
Second, freedom is a relativity theory, to each his own. Hence there is no absolutism of freedom, nor is there absolutism of regulatory requirements by which such freedom can be secured.
No market constructs we have built, in the U.S. or elsewhere, are free. Simply because we have not properly defined the relativity theory of freedom that could embrace the full scope of the human capacity of this world.
