The same point as any online game where your identity is hidden. It allows kids and imaginary tough guys to talk tough and avoid the consequences. This one just allows you to buy your way to the virtual "real warrior" status.
The point is to grow big, get 750m attack and spy attack in BFA, conceal all your equip, hide your allies, then merc around with 400/200/150/150 stats. Hit aff for 150 damage an' see the faces of yo clannies.
