As we've seen over and over again, when consumer products become commoditized, their retail prices eventually converge on the cost of production, and competition forces that cost lower and lower, until the market price reaches a technologically-determined minimum range and stays there, so that producers are unable to extract any meaningful profit from the activity of manufacturing and selling the product. Simultaneously, market competition relentlessly drives innovation, functional enhancement, and quality improvement so that the end-state products are generally remarkably excellent, powerful, and high-quality items produced for the lowest possible cost, and provided at the lowest possible price.
Since little or no "surplus value" is being created in its delivery, this end-state product of competitive capitalism is arguably equivalent to an ideal Communist production outcome--maximum benefit for the consumer masses, with no profit for the producers. In this way, the free market eventually forces many self-interested profit-motivated private enterprises to function as if they were public-benefit communes in a planned economy. Ironic.
