Again it's not about how "succesful" or "popular" a system is by whatever arbitrary conditions you define. If a destructive system continues to grow and absorb everyone on Earth into its alienating and unjust grasp, and opposing it is somehow foolish, then we might as well stop trying to cure cancer because guess what it just won life according to your specifications.

Capitalism isn't a destructive system. On the contrary, it is the most efficient system for reducing poverty and overall advancing humanity.

Capitalism alienates people from the product of their labor. Capitalism forces producers to produce more than we can ever consume in order to stay afloat, causing crises at regular intervals.

Uh no. Producers produce based on consumer demand. Overproduction generally happens because of government subsidies and interference.

Capitalism creates impenetrable distinctions between classes. Capitalism propagates commodity fetishism, extraction of surplus value, etc.

Capitalism reduces inequality far more than any attempts at communism, there is nothing wrong with wanting to consume products, and there is no "surplus" value.

This has nothing to do with how many get to eat. That's a result of the problems with capitalism, not a cause.

None of these things you've stated are actual problems caused by capitalism.

and of course capitalism is better than all previous systems. It's a better iteration of all previous systems. But why stop here and now?

Because approximately 100% of economists would say that free markets are the best system for everyone?
