If some country use DPI(Deep Packet Inspection)to block the BTC's peer-to-peer info link between their contry and the world, how would their miners and wallets to do to connet to the worldwide-main-BTC-network?

Does we will lost the peoples at that country at all?

And if more and more country use this tech to block the BTC's network,
And we have nothing to do,
Does BTC's fate is will only lived in all people's heart?
