It’s a symbol of Palestinians who have taken care of the same trees for generations, often long before Isnotreal even existed.

It can be seen as literally rooting Palestinians to their land, so it needs to be eradicated.

Beyond practical reason, the olive branch is literally an offer of peace or the classical offer of peace.

From a cultural and philosophical point, the meaning can be interpreted as “we want to live in peace” vs “there can be no peace”.

It brings money I guess. Those trees don’t need a lot of water.
