The problem is that underprovisioning uses some statistical average that will fail on special situations. Content streaming is so common now that there are peak hours where almost everyone is streaming video. If ISPs need to have that use case in mind, it should be possible for them to sustain that demand 24/7. If they don't do that, it's for one of two reasons. Either they can't sustain peak demand and they are trying to disincentivize usage, or they can handle a heavy demand but want to charge extra for off-peak bandwitdh usage, thus earning money for an already amortized infrastructure.
