There's a lot that's fundamentally wrong with this comment, but I think I can hit the core pretty narrowly. You cannot disentangle capitalism from the state, the capitalist state is not outside of capitalism but is instead a core function of it. Corporatism and cronyism are not in opposition to capitalism, they are a later stage in capitalist development, as compared to earlier capitalism when markets are highly underdeveloped and instead very decentralized and anarchic.
You also have a deeply moralist analysis, not a materialist, logical analysis. There is nothing inherently good about private property rights, and justifying the theft of surplus value on the basis that it is already common practice and would require violence in the form of revolution to change it is a moralist argument. It is just as easy to say that the everyday violence of theft of surplus value is a violent attack on working people, who create all new value. We must make scientific, materialist arguments, not simply rely on emotional soundbites.
You also ignore imperialism as a function of capitalism as it develops. The expansionist nature of capitalism causes it to dominate developing countries, where a share of the spoils are used to uplift the imperial working class. This is why the poor often get richer in developed capitalist economies, not because capitalism lifts all, but because developed capitalist economies shift their greatest contradictions to the international scale.
When you move on to socialism, you are entirely wrong. For example, the marketization in China is found in their developing industries, where markets do play a progressive role. However, in their developed and critical industries, China uses central planning. This is because planned economies overtake marketization when production advances to the national and international scale. It isn't a binary planned/market distinction that socialists advocate for, it's instead looking at the level of development of the productive forces and using the correct method accordingly.
Monopolies are an inevitable result of capitalism, because as technology improves, it requires more input to maintain. We cannot simply break up monopoly without inefficiently destroying productive forces in the process. This is where cronyism and corporatism, as you describe it, come in. Socialism and planned economy solves these problems by using the developed productive forces according to scientific planning, which is far more efficient at this scale (and is why China is doing so much better than capitalist economies).
Even more totally planned economies like the USSR saw some of the most rapid economic growth on the planet. They did not introduce starvation, they took overwhelmingly backward societies and brought them at and beyond their peers in rapid time. Life expectancy doubled between Tsarism and socialism in a matter of decades. Famine, while common in Tsarist Russia, was eliminated by 1935 outside of wartime. GDP growth was extremely rapid, all without running into crisis of overproduction or falling profitability:
You write a lot about what you "oppose" about capitalism, but without a coherent understanding of the totality of the system, you are reduced to unactionable moral platitudes, rather than concrete actions that can be taken. You remove the state from the economy and pretend it can be made to work both in the interests of the people as a whole while also shrinking, despite the fact that capitalists prop up and dominate the state as a co-evolutionary process.
The solution is socialism. Planned economy for developed industry, marketization limited to developing industry, and as all industry develops, transition to full planning to a collective and scientific aim.
