> Unless granted by a government, monopolies don't exist in free markets.
You made that claim, it's your responsibility to prove it first, not everyone else's to disprove it after you've made a flat, unsubstantiated claim.
What is your definition of "monopoly" and "free market"?
If I define "free market" as any market which is incapable of forming a monopoly, then yes, your statement is trivially true. But it naturally dis-includes a wide variety of markets that actually exist and may actually have monopolies.
