Having someone who goes through a list and cross-references the price of every screw and soap dispenser against the market rate to ensure they're not being scammed incurs a huge cost. Especially since the US government is buying billions of various supplies every year.

Your logic is the same as thieves who say, "It's not my fault that I stole their wallet. They should've put it in a slash-proof backpack and locked it with a combination lock that isn't easily picked." Sure, some degree of security and caution is good. But not defending criminal behavior is better.
