I don't think pH works the way you think it does.

Neutral pH is 7, things with a lower pH are more acidic Things with a higher pH are basic. So Carbonated water, with it pH of ~4 is a much stronger acid than something with a pH of 5

ah, I can see how you could read my last statement like that, but we're actually in agreement.

Carbonated water's acidity puts it at a lower pH than the acidity needed to start demineralization, so carbonic acid can cause enamel erosion.
