Zooko's triangle simply asks whether we can overload a string to do three
things.

The fallacy is that overloading is a good thing.  It's not.  It's an anti
pattern.

Once you see that overloading an identifier to do two things is a bad
enough idea, overloading it to do 3 is even worse.

So how do you solve the the problem.  You use the right identifier in the
right place, and use glue aka indexes to link identifiers about.

That's the fundamental value add of linked data.  And if you look at
websites like facebook they solve this use case using 3 different
identifiers

- Full Name as user facing
- Log in with email or phone etc.
- Primary key in the graph protocol as your WebID

The paradox of Zooko's triangle is that people think it needs solving!
