none of these are reason for the country not to demand transparent data for monitoring.

Being able to monitor things properly has high societal value - it prevents fraud (more data being visible makes it harder to fake). It prevents skirting regulations, and makes it easier for competitors to sniff out high margin opportunities (which serves to break monopolies in some sense).

Not to mention that statistics collected could have value in aggregate in research sometime in the future.

Like auditing and accounting, the country should mandate transparent data reporting of utilities usage for all industries.
