Also note that planning and central planning aren't synonymous. A central planning process makes more efficient use of planning resources, but that doesn't help if the plans it produces are themselves inefficient because they're based on five-year-old statistics someone faked for their personal gain. So far, decentralized planning seems to be more robust overall, and the additional decision-making overhead is small compared to the cost of actually moving things around.
In that sense, it's not even the case that food distribution is currently unplanned; a great deal of effort goes into determining what quantities of various foods should be transported to warehouses all over the world in order to meet future demand. The problem is just that the planners are optimizing their own profit, and keeping the largest possible number of people well-fed isn't profit-maximizing currently.
Of course so can technological change, but it's not like efficiency is just some dumb irrelevancy.
People need to get over the idea that a free market is the solution to everything?
To be clear I’m not advocating centralized planning, or any specific planning method. I’m simply pointing out the free market has specifically failed at food distribution. Or at least, you're going to need to contort the definition of success to get the free market to meet it.
People need to get over the idea of efficiency and centrally planned. These are not necessary qualities in order for humans to prosper.
