My example was a situation where we would benefit from a public blockchain solution in terms of more efficient administration, but were unable to use it because of ecological concerns. In that situation we already needed the product, and the improvement removes a barrier.

That's what I'm doubting. Ecological concerns etc. are a problem, but in my experience public blockchain solutions fail earlier, at the stage where one asks "would there be any benefit" before asking what the costs might be.
