>> That costs the government nothing The costs are actually substantial, but measured in things other than money.

I've lived in a place where selling price was below cost price for electrcity (with a Govt run electricity production.) Ultimately the price is paid out of the budget, which in turn is not infinite. Pressure on the budget in turn leads to redicing costs - like proper maintainence. There's some serious long term pain that is at the end of this path.
