Is it possible that bitcoin community along with core developers introduce new bitcoins into the system for the good cause?
The reward schedule and therefore the amount of bitcoins in circulation are central rules of the Bitcoin system. Changing the rules to create additional bitcoins would be incompatible with the protocol and in contradiction to the social contract the Bitcoin community formed around. Breaching this social contract that is central to Bitcoin would destroy confidence in Bitcoin's value.

So, while it would be technically possible that more bitcoins are created, I am sure that the idea to change the protocol to bail out business ventures would not gain the overwhelming support necessary to implement it. It seems more likely that investors would use contracts or insurances that work on top of Bitcoin to hedge against the risk.
