That's why I put it in quotation marks. Capitalism is heavily regulated in every western nation, perhaps every nation.

It existed today, so, yes it has. Capitalism describes the global mode of production, not just the United States economy. We haven't already forgotten the anti-suicide nets at Foxconn, have we? Without the margins that cheap foreign labor provides, the insanely high growth target required to please investors in a Capitalist economy can't be achieved.

I think we're fixating too much on purity of the word "unregulated." If you'd like to offer a different one I'm open to it - to me, the closest example of "regulated capitalism" is the PRC's State Capitalism, however it's a poor example given the atrocious working conditions there and the massive wealth inequality.

"Unregulated" to me doesn't mean "literally no regulations." To me it means, the owners of Capital have a very large amount of power, to the point that every regulation on them is an uphill, nigh-unwinnable battle. See: pushes for 30 hour work weeks in Europe. Or, see: pushes for socialized healthcare in the USA. I think we can both agree that the USA will never have socialized healthcare so long as the health insurance companies wield so much power and influence!

Because Apple under Steve Jobs worked because Steve had full control. Zero chance they become successful run by committee or group ownership or whatever. And they also needed venture capital in the beginning afaik.

I don't think Apple could have existed as it did under Jobs in any other system.

Apple's primary value driver (when it mattered) was luxury margins on mediocre tech. Without rampant demand, you don't have market stratification. If substantial regulation like the DSA existed in 2014, Apple's business model would look radically different today.
