We do require food manufacturers to 'open up' their production processes by printing every single ingredient on the packaging, plus a comprehensive review of the effects of the food on the body in the form of nutrition facts, caffeine content, alcohol content and allergen content among other things. Quite what the equivalent procedure for software would be is left as an exercise for the reader, but it's not as simple as 'government says so'.

The trouble is that the effects of harmful software are much less obvious than harmful food.
