Without repeating the same boring arguments about whether everything should be covered on Wikipedia, and just stipulating, whether you truly agree with them or not, that we'll confine ourselves to Wikipedia's policy of requiring that articles both assert and document notability: Doesn't it stand to reason that most "hackerspaces" aren't notable? Wikipedia doesn't even have coverage for every major office building in…
Why is inclusionism so bad? So what if we had a wikipedia article for every office building in Chicago or every Pokemon out there?
We probably should not have a Wikipedia article for every hackerspace in the world.
We may want more articles about hackerspaces on Wikipedia.
If we do, it does not help that almost everybody who has ever gone so far as to give their planned hackerspace a name has probably also added a (crappy) page to Wikipedia about their planned project.
