The page referenced discusses the need to have zero config-time dependencies between social networks. A full open system must exist.

I don't see how that can be in webid powered interactions.

Assuming that the foaf cards are stored at https endpoints, with server certs issued by x, both issuer net and relying party net have to agree on x (and implicitely outlaw y issuer of server certs, much as Mozilla outlaws cacert.).

If net 1 says I accept Tunisian govt server certs authenticating the channels delivering foaf cards, but  net 2 say I specifically don't, this introduces a dependency - and a config time need for bilateral setup (on which x candidate both can accept).

Of course, both might punt to a third party (and both accept any and all server certs endorsed by that common entity, whosoever it endorses). But this merely moves the negotiation point, of which endorser both can live with. For example, I, us govt, will not cooperate with any such endorser, if it endorses Cuban server issuers. For euro folks trying to book a holiday in Cuba using a Cuban travel agent, they of course need their social net not to enforce such (policy) exclusions. They need the net to work for them when interacting with Cuban businesses (even if it doesn't work for Americans).

Summary, trust point negotiation seems unavoidable, for the server certs that underpin global webid. And it happens at config time, using policies set by the social nets (not by subscibers).

It might be tempting for w3c to mandate  : the world must use at least 1 centralized endorser (the us govt, as reflected in the dns name  registrations) But this means those parts of the web that are unwilling to accept a us monopoly probably would refuse to adopt the technology (given the nature human politics).

For us/Cuba examples above, swap lots of other examples: china/Taiwan, Russia/Ukraine, Britain and France ( :-) ).
