The consensus models without the payment mechanism all undermine the utility of a blockchain.

Proof of Work and currency are inseparable, it is all interrelated to the design of any application using the blockchain.

I used hyperledger and even the example projects from the instructor were talking about all the threaded operations it can do, if there is no cost to the computation then randoms are DDOSing all the nodes in the system for no reason, which is exactly what happenes in real world hyperledger consortiums. Its dumb.

Either accept that speculation is a use case or move on.
