As a libertarian I try to make it clear that free markets can’t exist in the modern world without government activity.
In the prehistoric world, a person with something to sell or trade could mostly do so without interference, because everyone had similar physical power, making robbery more dangerous than it was worth.
But once power structures started accumulating: armies, governments, powerful families, etc, the only way to maintain free trade is via government actively maintaining that secure market space.
So the natural deterrent of coercive economic interaction (get injured when target defends their stuff), got replaced with the artificial deterrent of law enforcement (go to jail when target reports your theft).
Free markets need to be level and fair, and it takes government firepower to counter all the other firepower and level the negotiations out. When people can negotiate without fear of violence reprisal, they can freely enter or not enter whatever set of economic arrangements are best for them.
Free markets mean people can enter the market and do whatever kind of business they please so long as someone else is willing to take that deal. You can’t do that without a large effort to keep the space clear of criminal coercion.
That’s an extremely simplistic view of commerce and human history. Robbery was very common before government. Robbery is still very common, but less so.
Fraud and dangerous products run rampant without government intervention. Basically, without a government to protect you, the likelihood that a mega corp will sell you something that will kill you is super high. Just look at how much regulation has improved auto safety in the last 70 years. And appliance safety, medical safety, travel safety, food safety, etc.
The kind of world that libertarians pine for is the kind of world that would kill them in a month.

And this:
