 It's not arbitrary, it was picked because it makes spending inputs cheaper than creating new outputs.

 The "4x" is arbitrary. The discount in general not.

With "arbitrary" I mean there is no scientific reason why exactly this number is the correct one.

 It isn't arbitrary, it's the smallest whole number where we cross that threshold of making inputs cheaper
