You and me too buddy! 
Quite a few old folk on this forum hey Gosh, I’d forgotten that was how I did things in the days of dial-up. Thanks.
I think there’s a more than a substantial difference between ICANN and the suggestion to limit the number of domains, public and private Ids per account. They’re totally different IMO!
One is centralised, can be taken over or act without accountability. Classic centralisation risks, with added human “frailty”
The other, is a technical choice to ensure elements of the network (in this case the human controlled elements that we know can’t be trusted!) will find it harder to engage in centralisation of network capital (scooping up identities into their own privatised ICANN to do with what they wish).
Like the network measures to inhibit spam, these account limits don’t stop people having as many ids and domains as they want, they just impose a “cost” for doing so that makes it harder for a human to grab and control large areas of network (ids/domains) and human capital (spam/attention).
I see them as trying to defend against centralisation, and not a centralisation risk in themselves.
