Who is arrogant there? It's not an issue not to keep in touch every 3 weeks with someone. When you have a child, you just meet new people, parents of your child's friends for example. Relationships don't disappear, they pause, when you get back to them, it's like riding a bike, and if you don't get back to them, it's ok. It's what you do with your life which dictates who you meet, and who you have relationships with. Just live your life, you don't have to try and hack everything... If you really need a system like this, why not, but even I who suck at keeping in touch feel this is overkill and unnatural.
Yeah, that's what I'm saying. This system is terrible advice for someone who isn't really struggling with people, to such a point that it's detrimental to his wellbeing.
