I'm seeing lots of discussions and press releases about intentions to regulate blockchain dissociated from cryptocurrency with intention to apply it as a validation network to industry, banks and government.

Assuming that we are not on a solar powergrid, my question is:

If there is no currency involved, who would join a mining pool and spend 1365W/h (actual Antminer S9i power consumption) to validate blocks for free?

I read an interview with the president of Federation of Industries of the State of São Paulo (In a raw translation) saying:

"[...] With an eye on the impact this technology will have on the entire industry chain, which can reduce costs, waste and bureaucratic processes, as well as increase productivity [...]"

What is the point to save X money with papers and bureaucracy and spend X*10^3 with electricity?
