Because it’s damn hard. 
But people are trying. Myself included.
Not sure where you are (Indonesia? the toponyms sound East Asian – Tulunggagun, surabaya), but some of us will be social innovation camping in Medenine, Tunisia, where a group has formed around a young woman called @Yosser. They want to create just that kind of space. Not in New York, Berlin or Beijing, mind you: in Medenine, Tunisia, because that’s their community and they decided it needs one. Maybe you want to join them?
Welcome, anyway
