In a space where every founder and investor will evangelize their preferred project faithfully or not (often times somewhere in between), is it at all possible to reliably broach the topic to the savvy uninitiated about problems and solutions in the space, and offer people ideas such that they can develop an informed perspective?
I don't necessarily wish to argue, but I do want to hear the most competent and difficult concerns to address - more than low hanging fruit.
I should add one argument before responses flow in: the perspective that a blockchain can exist without a currency is most often a reflection of ignorance on the special type of 'security' (meaning, cost to rewrite history) a blockchain offers. The view that a blockchain with no currency makes sense does not pan out - and if it did it would be a greater innovation than Bitcoin was.
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.
Also your last paragraph is wildly off base. There are a number of PoA chains being prototyped by industry consortiums.
A blockchain funded and controlled by a central authority is just a slow and unnecessarily complex database --- easily implemented to better effect with less effort/cost by traditional means.
