Unfortunately, most people that are interested in Bitcoin are doing things based on personal profit.
Hopefully it can be used as a tool for change, because as you pointed out, it makes so many things easy that were not possible before.
As time goes on, I would not be surprised to see charities and other social causes become involved with crypto-currencies.
Social serving activities all go with the legal path, then How we use this decentralized currency to charity or orphanage. For all this first bitcoin should get accepted by the government then all the usage possibilities are there.
