Bitcoin is community based system. No governing party. So, to help the community grow ad to spread bitcoin, we need new start ups. But people may not invest bigger for new technology. So crowd funding is the only solution to kick off those start ups. It will help bitcoin to grow rapidly.
Sorry but I don't understand what is the connection between your post and mine (which you are quoted). If you think that Coinbase isn't a start up which don't help the community I don't agree this. Its services are for the community more than needed. Anyone need a place (secure place) when to put their bitcoins. Coinbase is one of the bests in this direction.
