You're missing one of the basic issues with bogon sources: they are often advertised bogons, IE the bad guy DOES care about getting the packets back, and has, in fact, created a way to do so. This is usually VERY BAD traffic, and EVEN WORSE if a user goes TO a site hosted in such IP space. So, Bogon filtering has value beyond mere spoofed source rejection.
Unmanaged (or semi-managed) routers probably should not be running BGP or other exterior routing protocols. Unmanaged routers with BGP provide more opportunities to create havoc and mischief.
