If such networks collapsed how could most people keep bitcoin secure? Or run the computing power to power the network?
With gold, money and other valuables you can carry them with you and hide them.
What can be hacked are exchanges and wallets. You can keep your coins out if these as long as you want and carry them as gold or cash and do in place transactions whenever the network is available. You can even use physical coins, which are simply piece of paper with the key written on it. The receiver would need to have a connection to verify that the funds are still there though.
No jurisdiction has any power over who owns what coins. The best they can do is to physically extract the fund from person like extracting any secret(torture, punishment if they don't comply etc.). If the person of interest dies with his secret, the coins are gone forever because the premise of BTC is that it is kept in a distributed database that can only be changed(and the only possible change is addin new records) with cryptographic validation and governments don't have a power over mathematics.
