On the other hand, if you use a unit of bandwidth there's another unit waiting for you.
That's an irrelevant distinction as bandwidth is a scarce resource (in economic terms). Instead of being separated into physical units (e.g. liters, gallons, etc), bandwidth is separated into temporal units (e.g. KB/second). There are a finite number of these units at any specific time. If somebody is to use all those units at once (the full pipe), other users are deprived of bandwidth.
Therefore I agree with the GP as those who use more pay more (just as with everything else).
If the rates are fair, pay-per-use is a good idea -- certainly better than arbitrary data caps that might get enforced god-knows-when
