It is important for blockchain networks to have high availability as some users have time critical applications. In the case of BTC we would like to be able to trade at all times. If you became aware of information that would affect the price you would want to be able to act on that knowledge immediately. It would be lame to have to wait until monday morning for the banks to open. If you had your medical data stored on a blockchain and you had an accident and required surgery it would be very important for a doctor to be able to that information readily available.
The financial incentives of the blockchain that rewards miners with the block subsidy means that if part of the network goes down a miner in another place can provide more hashpower and be profitable. The fact that miners are distributed around the world means that the probability of at least one miner surviving a catastrophic incident and for it to be profitable to do so is very high.
