Using URIs is a great way to scale.

Not sure this characterization is accurate.  Users see URIs all the time,
for example hyperlinks, and in the address bar.  What you are referring to
(I think) is a user experience, that of typing a url into an input box,
rather than, clicking one.  It's clear that users are not trained to do
this, in the same way they have been trained to type in email addresses at
this point in time.  Your language indicates you have strong view on this
topic, further discussion my not prove fruitful, let's see. :)

Facebook use firstname lastname, which is what I think most people are used
to.

That's where the web can help, it is good at namespaces.

I dont know what this is?  Is it an email address?  An acct: URI?  A sip
address?  An xmpp address?  Any number of other addresses.  There's a
scalability point of failure right there.  Let's say it's an email
address.  We're back to the centralized model where the big email providers
dominate.  Can we do better?

I feel the opposite.  To scale payments you need a first class identity
system.  Or you'll hit a wall scaling -- ripple and bitcoin are good
examples.  Meaning no disrespect to either system, both have very cool
features, just scalability is not one of them, when compared with the web.

Persona is being shut down, imho, due to this bad design decision.
Webfinger isnt far behind it.  Why not just use WebID?  It's best of breed
in this class.  I suspect the usual biases will kick in at this point.  But
I'm more than happy to let implementations do the talking on this one.

Working on it! :)
