Default PK - To AutoNumber or Not To AutoNumber - That is the Question

I agree but I think many people see "autonumber primary key" as always
being the answer, the panacea. I'm not sure whether the blame lies
with the "I tend to use Autonumber PKs for most of my tables" brigade
or whether it's Access's "A table must have a primary key for you to
define a relationship between this table and other tables in the
database [incorrect]. Do you want to create a primary key now?" but,
if proposed designs posted in these groups are anything to go by,
consideration of candidate keys tends to go no further than
"autonumber primary key"
