The PoW isn't meant to elect the next miner. It's meant to ensure the integrity of the chain and maintain a lead in the work cost for the honest chain.

Transactions are already signed and can't be forged. The only reason for the chain to exist is so that everyone knows about every transaction, to eliminate the double spend problem.
