Because (I imagine) you can't really brute force it. If you only have 3 or something tries, it doesn't really make that much of a difference. And the person that stole your card would just try 123456 instead of 1234 etc and roughly would have a similar chance of success |

That said, guessing the PIN isn't the only attack; longer PINs also means that you have to "spy" more digits, which can be significant if the "spying" method is not 100% reliable.
But yeah. I guess it doesn't matter as long as you have a lockout mechanism.
