Because typing that takes longer? You're missing the point of an
usability feature.

better do (without pipes and cheating):

for file in *zip; do
  test -f "$file" && action...
done

In this example, you could use the even shorter: cat *zip
But I see your point - there are indeed cases where pathname expansion on 
redirections is utile, and since it's also conforming to POSIX for an
