Well, that's not quite true. If it's only one or two and they don't filter their own customers, an ISP can simply get a T1 to everyone who filters and keep their small blocks working.
If that became a popular plan, it would be an incentive for large providers to filter as aggressively as they could get away with, to force more people to buy connectivity. Before long it would no longer be viable to run a T1 to every such backbone. -- Shields, CrossLink.
