This is the same problem as bootstrapping a cryptocurrency. There are various ways, none very good. You could mine it with proof of work. You could distribute it widely to important figures, such as operators of big relays (as long as the internet stays up, there are going to be people sending messages inter-city through the internet instead of by plane). Perhaps you give half to big relay operators and half to their currently connected clients, that would incentivize people to get on the network early and try it out.
