A total free-market is that you let the market decide everything - no rules or regulations stopping the market working to the best of its ability.
This is the ideal case in theory, a pure efficient working of the market.
In reality this cannot be allowed to occur, as you need safety rules, environmental legislation, you need to make sure basic services are provided to those who can't afford them, you need to provide access to the market for those who have no access. This can still be a free market, but working within a framework.
Too much framework, and it impedes the efficiency of the free-market.
Not enough framework, and it won't benefit the wider population.
