I think you're misusing free market here. The free market theory when broken down to its most pure form is natural supply and demand come together in a voluntary and transparent and non-manipulated way which ultimately leads to the most efficient use of resources. The merits of the system is that the most efficient use of resources tends to enrich/create a higher quality of life for the most people possible.
That last part is very important because it is why people have been so passionate about the idea for hundreds of years and fought and died for the ability to practice it.
A free market is not using market mechanics and psychological tactics(techniques) and coercion to make other market participants work against their own interests and in a way that doesn't at all take natural supply and demand or efficient distribution of resources into account so one person gets enriched at the expense of everyone else.
Also, isn't putting in a limit order on binance putting in whatever price you want? Am I misunderstanding what you're saying in this part?
