If I may continue the discussion...
If the earth is private property (capitalism requires as much), then it follows there must be government otherwise Darwinian principles take over. I can't imagine anyone wishing for Darwinian principles (e.g. might makes right) to control society as opposed to human planning and intelligence (unless it's a monopoly which tends to harm the general population).
Assuming we will not dismantle governments anytime soon, either we can have Darwin, a monopoly, or a form of public government. We currently live in a monopoly government where the business class, a highly class conscious group, are aware they participate in "
investment politics." In other words, they fund campaigns to construct policy in their favor. This is nothing new but is reaching unprecedented levels compared to the last few decades.
If government is to exist (it does and will indefinitely as opposed to Darwinian policy), then it
should serve the general population, not just a minority or monopoly. In order to serve this population, the absolute first and prime issue is ensuring
access to food and water without which the population ceases. I am not saying the government must deliver food to every person each morning. There is a crucial difference: gov't must provide a means, not the end. Whether that's providing private property for self-sufficiency or ensuring an adequate supply of jobs to meet the demand for earning one's access to adequate sustenance. That isn't asking very much since any jobs available should be designed to contribute positively to society's functioning and advancement.
