I believe you meant to title thread "Engrish improvement plan".

Articles serve important purpose in English. It's like "wa" and "ga" in Japanese.

Plural form is even more important and I do not know how Japanese gets along without it.
Hell, I cannot find it in me to eliminate plurals from this post.
Third person singular is very useful for indicating gender.

You is correct to say that "be" forms is silly, but they have been around for so many centuries that eliminating them looks really weird.
