Yeah, my setup is purely for my own security reasons and interests, so there's very little downside to my scorched earth approach.
I do, however, think that if there was a more widespread scorched earth approach then the issues like those mentioned in the article would be much less common.
If you actually wanted your site or service to be accessible you’d run in to issues immediately since once IP would have cycled between hundreds of homes in a year.
IP based bans have long been obsolete.
In such a world you can say goodbye to any kind of free Wi-Fi, anonymous proxy etc., since all it would take to burn an IP for a year is to run a port scan from it, so nobody would risk letting you use theirs.
Fortunately, real network admins are smarter than that.
