Markets depend on regulations.
Free market absolutists don’t know what they are talking about.
The actual originators of market capitalism, most famously Adam Smith, but also proponents like Milton Friedman, had no such confusion.
In reality, today’s free market absolutists don’t get their ideas from economists (even free market economists). Instead, they get their ideas from terrible mid 20th century novelists (I’ll let you figure out who I’m talking about), who didn’t know much about how anything worked, never mind economics.
“There are two novels that can change a bookish fourteen-year old’s life: The Lord of the Rings and Atlas Shrugged. One is a childish fantasy that often engenders a lifelong obsession with its unbelievable heroes, leading to an emotionally stunted, socially crippled adulthood, unable to deal with the real world. The other, of course, involves orcs." -- John Rogers
