Capitalism isn't that nebulous, we can start with the basic wikipedia definition:
Capitalism is an economic system based on the private ownership of the means of production and their use for the purpose of obtaining profit.[a] This socioeconomic system has developed historically through several stages and is defined by a number of basic constituent elements: private property, profit motive, capital accumulation, competitive markets, commodification, wage labor, and an emphasis on innovation and economic growth. Capitalist economies tend to experience a business cycle of economic growth followed by recessions
Now what's the central problem here? I'd say it's definitely capital accumulation. The problem is that capital is power, and it has a strong tendency to grow exponentially. Once capital becomes concentrated enough, it will subvert the government via bribery and any democracy via privatized propaganda. From an anarchist perspective it's just another unjust power structure, but veiled behind layers of false meritocracy and false consent.
If you make it impossible for private individuals or organizations to accrue large amounts of capital, you effectively no longer have capitalism but you may still have a market economy.



Someone brough up a theory that it's a "symbolic punishment" for a journalist:
remove the eyes so you cannot see
remove the brain so you cannot think
remove the larynx so you cannot speak (the larynx contains the vocal cords)
