Clearly you miss the point or don't understand politics, if you think the matter or comparison I made has anything to do with finitism. Politics has everything to do with conflicts in wants. For example, some people want free speech, and other people don't want other people to be able to spread lies or what they perceive as lies. Do you see how these wants are at odds with each other, or that two people can have opposing wants? Such conflicts can arise wherever humans interact with each other, and the internet isn't different somehow because it is less finite. I mean, do you think there aren't people out there who don't want to police the internet?

Simply, put, politics is not limited to matters of finitism. And the example I gave, is a perfectly fitting example of where politics is evident.
