You should research WeWork before drawing any firm conclusions on this topic. They've spent enormous amounts of money experimenting with what people want in coworking space.
I don't know that WeWork works. They certainly don't make money. I'm not sure coworking space is a viable business at all. No one seems to have cracked it yet.
I think that good networking events have all the benefits of coworking with none of the drawbacks.
Most coworking spaces just end up being loud offices with not much community interaction anyway. Might as well do work in a true office and then network somewhere nice and social.
