Just like totally free (unregulated) capitalism in a market will automatically lead to a monopoly.
The only monopolies that exist in unfettered free trade are those that already provide optimum product or service at optimum price for the consumer. Otherwise, a new entrant will either provide a better solution at same price or same solution at lower price, thereby eliminating the monopoly.
This is all quite foundational.
So with that understood, are you trying to malign the very existence of such a monopoly?
A new entrant will get squashed by the all powerful monopolist, as happens all the time in the oligarchies you can observe in poorly regulated markets around the globe. They get bought up, and their ideas either implemented by the monopolist or shelved (e.g. Shell buying green energy innovations. They have a big shelve full of them, waiting for the right time).
