I'll pipe up.
I'm of the opinion that the private and lawful sale of goods should absolutely and always remain the business of private parties. I'm not super interested in any other party -- particularly one that has a three-letter acronym -- having any knowledge of what I own or how I conduct my own affairs.
That said, I'm a contractor. A large part of my worksite hygiene involves CYA. When I'm building to engineering drawings, unless I have explicit dispensation otherwise I will build *exactly* to drawings even if the final product is not what the client intended. When I work on or modify an existing structure, from a certain standpoint I "own" that structure and I will go out of my way to make sure that nobody else can non-obviously then change my construction or the substructure and blame any consequent problems on me.
If I want to buy a firearm and someone insists on an FFL because they're covering their own ass, well, that's their prerogative to do so and I won't hold it against them. If I elect to not use an FFL (either because of cost or personal reasons, well, that's also my own choice and nobody is forcing me to purchase anything from anybody.
I can sure respect a good CYA and wouldn't hold that action against someone.
