A free market means that there is an absolutely level playing field. All transactions are completely transparent and buyers can assess all the sellers - and such a market doesn't exist anywhere. I doubt it ever has, outside barter economies at village level.
In today's complex economies where governments interfere to subsidise or tax many aspects of the economy, in many cases for entirely virtuous purposes, it is impossible to have an absolutely level playing field. Nor can we cannot assess every suppliers offer. Just how open and transparent is the domestic energy market where there is supposedly a free market, to choose but one obvious example?
The mistake that governments have made since the Thatcher era is to assume that opening a market up to competition makes it a free market. If it is so free why do we have to have so many laws to stop companies in this 'free' market from colluding and fixing prices, conditions of delivery, making life difficult for new entrants, running monopolies etc etc?
Then there are ethical issues, like those surrounding the manufacture of the inexpensive clothing we expect to find in every supermarket and chain store. What do we know about the manufacturing processes and human rights issues behind the cheap clothes and food we buy. Look at the way the recent Tesco debacle has revealed how many supermarkets bully and undermine their suppliers, in some cases driving them into bankruptcy.
'Free' markets are a chimera, like fairies at the bottom of the garden. They do not exist.
