While you could use f4 with white and make the claim that it'll lead to a Dutch setup, there are a few differences:

1) The Dutch is in response to 1 d4. With this move not played yet, black will have the oppurtunity to play d6 instead. This in itself allows this gambit to be effective: 1 f4 e5 2 fxe5 d6.

2) Black could also do a slower buildup with d6 and play for ...e5. It's certainly a different game altogether as white will find it much more difficult to keep control of e5.

3) Of course, black may just response with 1...d5 and then yes, it'll lead to Dutch positions with an extra white tempo.
