Heck, even if you want to blatantly ignore every other platform and site you can buy games from, which there are plenty, Valve gives devs a supply of Steam keys they can sell anywhere they want, they don’t even get a cut from those despite providing the bandwidth to distribute the files.

A monopoly on what? PC game storefeonts? Itch.io, gog, epic, gamepass, some are better than others, but steam isn’t anti-competition
They aren’t really a monopoly. You can purchase games elsewhere. They are simply the gold standard of gaming platforms.
