You need them because denoting reference style identifiers using angle 
brackets is an existing pattern in broad use. Isn't that pragmatic enough?

And what do you gain by leaving them out in a new spec? Do you seriously 
believe that <http://example.org/index.html> as opposed to 
"http://example.org/index.html" is a pattern unique to Turtle? Reference 
based Identifiers have be represented this way long before Turtle.

You leave stuff alone that's already in use. Being non-disruptive is the 
gain.

This isn't about Turtle its about AWWW. Angle brackets use existed long 
before Turtle.

What about References?

If you are dealing with parameters then why not represented references 
(URIs) using  ^^xsd:anyURI . Example
"http://example.org/index.html"^^xsd:anyURI
