This is only true if you ignore the fact that marginal land can often be improved, it's often considered marginal because it was misused and abused by earlier generations, or because it's not suitable for industrial agriculture's extractive methods. Small holdings traditionally made quite productive use of these 'marginal lands' but that way of life has been forgotten as industrial ag and society has supplanted them. Most of the UK's 'marginal' land for instance was covered in great forests, so there is great potential for climax community ecosystems to establish, these could in theory could be engineered to meet our all our needs and be far more productive than using this land exclusively grazing livestock. Don't forget that introduction of grazing animals is one of the biggest factors for suppressing natural succession in these ecosystems. That is not to say that grazing animals are to be avoided, or that all marginal land can be used to create food forest, but our lens of possibilities is distorted by modern agri practices.

Or you could just squat in an abandoned house in Detroit and raise shrimp* and marijuana. Land too marginal for agricultural production is kind of yesterday's news in the world of hydroponic factories, DIY micro-propagation, heme gene altered yeast distilleries, and detailed genetic analysis of a given cultivar's landrace potential.
