This would save the resources otherwise needed to 'mint' a PoW token. If youd like to get into the finer details of Proof of Work, then continue reading. Requiring a PoW token from users would inhibit frivolous or excessive use of the service, sparing the service's underlying resources, such as bandwidth to the Internet, computation, disk space, electricity and administrative overhead. While the rewards may vary from blockchain to blockchain, the purpose is always the same: to incentivize individuals to use their computers to solve the difficult math problems required for blocks to be mined.
