The cost of production is irrelevant. The sale price is determined by the supply and demand on both sides (supply of the product, and supply of money available to pay for it).
A market like ISPs is subject to natural monopoly because of the physical nature of running wires to houses. A true free market would see any competitor free to run their own wires and offer a service, but we don't allow that. We kind of did in the early days of electricity when people just strung up wires wherever they liked. It led to a lot of people getting electrocuted.
If there is really a large margin available for a competitor to undercut, someone will find a way to do it. And, as predicted, people are with options like Starlink and 5G hotspots becoming viable.
