I disagree for the following reasons, as already stated in an earlier 

1. Linked Data isn't about the needs of programmer, solely -- it is 
about giving everyone the ability to create and share webby structured data
2. Turtle is the only RDF syntax notation that satisfies the basic needs 
or end-users and programmers.

Not true!

People should be able to save the following to a local or publicly 
accessible file denoted using a file: or http: scheme URI :

I am elated about Turtle. You are expressing a specialized world view. 
The Web is for everyone and we should do everything in our power to 
accentuate that aspect of this powerful system, via Linked Data.
