If someone used a single address for every transaction, anyone looking
at the blockchain could link multiple payments to one identity.
Electrum is a deterministic wallet that can generate an almost
unlimited number of addresses. Simply stated, there is no way to link
addresses generated from a seed. Electrum addresses look exactly the
same as any other randomly generated address on the blockchain.
Unfortunately, I am not familiar with Electrum's implementation of
deterministic wallets, so I cannot reference specifics. Electrum
delayed implementing the standard of hierarchical deterministic wallets
(BIP 32) until version 2.0, but I am sure that it is similar.
