There are eight billion people on earth, so it’s even cheaper. Internet access is one of those things that requires infrastructure that gets cheaper per user as it scales up. At a global level, yes, internet should be ridiculously cheap per capita.

The cost we pay here in the US is mostly profit for the oligopolies that control the last mile. Licensing fees because they control access via legal obstruction. If I were to create a community server, it could be much cheaper as a non-profit cooperative, but for the cost defending from litigation from the established chains.

In other words, cost of the internet is inflated by force, not because internet access is expensive to construct and maintain.
