I'm currently in a non-WeWork co-working space. It's not clear what you mean with "The fact that no one can actually do real work at a WeWork was just icing on the shit pie.".
I guess it's good if you like to meet people. Not so much if you need a quiet space to work.
In this case, the free beer might be an intentional way to take "loud room I can't work in", to "laid back atmosphere I feel home in". The latter is false, but it's not as bad as being stuck with "loud room I can't work in".
Disclaimer: I work in a private office in a London WeWork and the free beer is a nice to have, even if it wasn't a consideration while picking an office.
