I’d like to see government make this mandatory for businesses over a certain size. The government loves

Some would opt out of this, which is why I imagine it would be
voluntary. Personally I’m not too concerned whether Big Brother
knows how many waffles or cartons of chocolate milk we’ve purchased
in the month, but I can see use for the data.
