user32114: What are the strategic ideas of the Grob's Attack?
Is it meant to initiate a kingside attack?
Or is it meant to grab space on the kingside and use that space to maybe initiate an attack in the center or on the queenside?

The ideas behind 1.g4? are not sufficient to justify such a weakening first move.
The grand scheme
In an ideal world, White's strategic aim after 1.g4 is to build as much pressure as possible on the light squares in the center:

They will fianchetto their light squared bishop, aiming at e4, d5 and even b7.
Pressure can be reinforced with c4, Nc3, and sometimes Qb3, d3 or e4.
Black's most natural defender of the light squares is a knight on f6. However, an early ...Nf6 will be ousted by g4-g5, kinda justifying White's first move.

The trick
But the main reason some White players are attracted to the line is that they gamble on their surprised opponent going for natural moves and stumbling into the Grob gambit's trap:
[FEN ""]
1.g4 d5 2.Bg2 Bxg4 3.c4 c6?! 4.Qb3

when all of a sudden the pressure on d5 and b7 gives White a huge initiative.
Note that all the moves played fit the grand scheme of attacking the light squares !
