It's a real product that I would want to use, and it's just happening to use a blockchain as part of the tech-stack because that was the most appropriate choice.
Is you try to shoehorn just some "blockchain" into a product or usecase, just for the sake of using a blockchain you already lost me.
Get multiple F500 organizations using it in non-pilot production use that is not treating it as a speculative asset.
Also your last paragraph is wildly off base. There are a number of PoA chains being prototyped by industry consortiums.
A blockchain is more than a VC scheme when the emission doesn't confer any advantage to its creators or to early miners.
Explain how the blockchain will be operated, funded and reasonably/securely perpetuated without involving either cryptocurrency or a central funding authority.
A blockchain funded and controlled by a central authority or group is just a slow and unnecessarily complex database --- wholly built around trust and easily implemented to better effect with less effort/cost by traditional means.
