Companies cannot be forced to sell their operating systems distinct from hardware if they choose not to. That's a ridiculous expectation. There is no market for macOS, only Macs, and that market is the broader PC market, which Apple is nowhere near monopoly power

Saying Apple has a "macOS hardware" monopoly is like saying Dyson has a "Dyson motor monopoly"

Companies get to choose what their products are, full stop
