A web server is just any software that can be accessed with web network protocols. This can look like a lot of things. If you have Python installed you can start a web server right now by running python -m http.server. localhost:8000 in a browset would then let you browse files via the (local) web.

What kind of server do you want to run?

Capitalism will not abide people not working just because they don’t want to. Even in rich countries like the US where imperialism and the undocumented immigrant labor underclass could provide everything truly needed to survive, capitalism requires that the population be exploited to realize even greater profits.

I mention imperialism and the immigrant labor underclass because work is still necessary for production and momentary examples to the contrary (e.g. COVID lockdowns) are an illusion built on the backs of the hyperexploited. However, if we were able to depose capitalism, we could focus our efforts on eliminating the need for work rather than building everything around profit maximization.
