1) What I'm protecting [my family and my posessions] is a lot more valuable
to me than a few seconds wasted by a spam that slips through.

to get in.  So the cost of checking who is at the door each time
someone knocks is manageable, but the cost of checking every incoming
email manually is not.

How is it less effort to be forced to check every incoming email than to
allow your computer to do some or most of that work?  You are not making
any sense.  You are advocating a system that is guaranteed to produce
false-positives and that avoids losing mail to FPs by requiring manual
sorting of email.
