Managing bandwidth based on a paid fee is a type of a bandwidth management. In analogous fields, we accept paid prioritization. Pricing/auctioning is a commonly used method for assigning resources efficiently.

If my ISP is hitting peak throughput at 8pm on monday night, it makes sense for high priority traffic to pay for priority (streaming, telephony, etc), while low priority traffic (bittorrnet, dropbox updates, etc) slow down because they are unwilling to pay.

I don't think outright blocking is justified or even purposeful slowing down (rather than speeding other stuff up). But i don't think treating everything the same is economically justified.
