Some do.

My ISP has two vlans on the cable modem system.
One with no peer-to-peer traffic at all, and the other has
no filtering.  You have to ask to be on the non-filtered vlan.

It cost them nothing to offer the no-peer-to-peer (and in fact
saves them tons of tech support time) so they charge nothing
more for this.

Non-peer-to-peer can send/recieve traffic to/from the
non-filtered vlan, so local web sites can be reached.
