One massive example is Louis Rossman.
I love Louis, he's done so much good. He's been trying so hard, but all of his 1000 complaining videos are 100% because of capitalism and he STILL loves it and says he's not a "commie". It just doesn't make sense. You're advocating for socialistic things, but you're not a "commie"? You have been fighting capitalism and its evil for years, and yet you're still a "free market man"? There are plenty that are like that and it never made sense to me.
I think there's a distinction to be made between free market economies and capitalism. Capitalism, with limited-liability shareholder corporations and such, allows businesses to scale and concentrate wealth in a way that markets by themselves do not, and that's where the problem lies.
Capitalism is more broad than that. The Soviet Union was state capitalism. Basically a capitalist economy with only one company, the government, and thus no free market (monopoly on everything).
A smidge, yes, but scarcity can be enforced. Which is what happens in capitalism, for the most part. Those with means undermine methods of creating cheap abundant supplies, because it would overwhelm demand and there would be no profit. It's not even necessarily intentional. There's just point in investing in an over-abundance of supply, as your returns would never make it worth it.
It's as much, if not more, about intention as means.
