Filtering the bogons does help, and everyone should perform anti-spoofing
in the appropriate places.  It isn't, however, a silver bullet.
it's necessary but not sufficient.
anti-spoofing is useful, but vastly insufficient, and hence not necessary
anti-spoofing eliminates certain avenues of attack allowing one to focus
on remaining avenues, and hence (as Vix stated) is necessary but not
sufficient.

it turns 1% of the technical problem into a massive social business
problem which, even if it was solvable (which it practically isn't),
would also be addressed by technical solutions where no spoofing is
involved.

but it would provide a lot of fun and soapboxes for wannabe net
police and vigilantes.
