Especially in most cases of home networks, the firewall is also the termination for the off-site link (DSL, cable, fibre, etc).

Unless you're co-sited with your ISP, that argument doesn't make sense, because there is at least one off site link between you and the ISP - a WAN link. :) In this part of the world, at the physical layer, my Internet link is a 4.7km DSL line, but by the time you get to the IP layer, the first hop is at least 150km. Hardly a "LAN" in either case! :-)
