The emphasis is on "alone".
Free market got some good sides, but it needs certain regulations.
Central planning alone is also crap ^^
And who decides the regulations?
If I want to buy something, and someone wants to sell me something, why does someone else have the right to get in between that transaction?
The reality is that regulations are a hindrance on the market. One of the reasons why they are so favoured is because big business likes to use them to push their smaller competitors, who can't afford the cost of compliance (lawyers, etc), out of the market.
