All that broadband access operators need to do is to a) enforce antispoofing as close to their customers as possible,

Many probably do so already. But as well all know, it only takes a few that don¹t to create a large scale issue. IMHO if we want to change this we need to (1) measure where and how anti-spoofing is not implemented, (2) contact networks that have not implemented with recommendations on how to do so (a la bcp38.info), and (3) failing reasonable response to #2 to start a public running list of networks that have inadequate levels of anti-spoofing (according to some reasonable standard, and probably more nuanced than a binary result).
