Maybe it's because it leaves the pawn on e2 so it can make its break to e4 in one move. Maybe it actually makes the kingside harder to break down, despite that it moves a pawn over there.
So here comes a little essay...
The direct fianchetto 2.g3 came to be considered the best answer against the Dutch during the 1920's already. Most reasons for this are based on the hypermodern ideas of Nimzowitsch & Co. that nowadays are part of the strategy canon.
Let's have a look at the logic behind this. If we compare the Dutch to its mirror opening, the Sicilian, we see that in the Sicilian White is able to break up the center by means of d2-d4 very quickly, which allows White to obtain good development and space advantage.
In the Dutch, the thrust e2-e4 can only be achieved by sacrificing the pawn, so if White doesn't want to play a gambit, a more strategic setup is called for.
In the pre-hypermodern times, players would unanimously play roughly along the development plan c4, Nc3, e3 - if possible after Bf4 - and then develop the bishop to d3. They would then find that Black had increased his grip on e4 either by setting up a stonewall (d7-d5) or by means of Bb4(xc3), b6, Bb7 (there actually were some pre-hypermodern players who new about the fianchetto, like e.g. Bird or Staunton et al.). With e4 firmly under Black control, it is difficult to open the center, allowing Black to conduct the classical Dutch kingside mating attack (like Rf6-h6 etc.).
Now, the hypermodernists had very elaborate ideas about the center and pawn structure. In their view, the fianchetto against the Dutch accomplishes the following:
- By bringing the bishop to g2 quickly, Black is discouraged (or even hindered) to bring his bishop to b7.
- Since f5 is occupied by a black pawn, Black's light-squared bishop also doesn't have immediate perspectives on the c8-h3 diagonal. Note that the pawn on g3 also accomplishes what Nimzowitsch called "Hemmung" in German (I have googled a lot but haven't found the English term, sorry). This means, that the f5-pawn is restricted and therefore Black has to resort to long manoeuvers à la Bc8-d7-e8-h5 in order to bring the bishop into play.
- The hypermodernists also weren't fond of committing in the center too early. Their view of an early c4 was that it only allows Black to play Bb4 and strengthen the grip on e4. On the other hand, the Black king's bishop lacks a better square than e7 (or g7) if White develops his king side first.
The above list is of course pure strategy but to this day is the thinking behind the notion of 2.g3 as the best move against the Dutch. If you'd like to have poker analogies, we could say that:
- 2.g3 is the GTO line
- Early c4 against the Dutch is similar to reraising with crappy Aces from the BB in PLO.
- It's well possible to play the non GTO lines as long as your opponent lacks the skill to exploit you...
