You own your Bitcoin as long as there is at least a single node out there storing its Blockchain. But it would be the only instance left that could confirm your ownership in that doomsday vision of yours.
You can think of Bitcoin as a kind of identity management system. The blockchain stores transactions mapping public keys to each other and monetary values. As long as you remember the private key matching your public key you can issue transactions on the blockchain.
Contrary to common belief Bitcoin is not stored on your hard drive, they contain only your private keys. The monetary units themselves, “UTXOs”, are stored on the network of Bitcoin nodes distributed all over the world.
