I would argue against the Capitalist system being functional. Capitalist propaganda has created a mythology of attributing to itself many accomplishments which should really be attributed to human labour. All of its flaws are cast off as “simple facts of life”.

Much of the foundational technology in communications, the Internet, and medicine were initially developed in government (public ally funded) labs, where profit was never a motive. All capitalism has done is give us thousands of variations of similar technologies, at the expense of countless other technologies - and in the process has forced humans into wage slavery / actual slavery, destroyed our coral reefs, and is heating up and polluting our planet - driving us toward extinction.

Even if we build the perfect solar panel, or do make it to Mars - where sustaining life will be much harder than sustaining life on Earth - that won’t save Earth, and it won’t solve the problem of the endless commodification and exploitation which is the capitalist system.

At some point we need to stop acting like mindless automatons and abandon capitalism, and work toward an actual sustainable system which isn’t hostile to life.
