What`s your opinion? Should we use such sentences according to normative grammar?
When Jim Loy said that he did not think of your examples. I am sure he would deem them inappropriate too.
You can say:
I do not want anything.
I do not want anything from you.
I can't disagree with you.
To me this is strange. What does negation mean? The way I see it, want is the negation of 'not want'. How can I decide which of the two is the negated version, once they mutually negate each other. So, in a way the first sentence is double negation too, only morphologically it is not explicit - there is no two no's.
In the third sentence, disagree means having a different view. Double is the negation because that dis- prefix is there.
Semantically, the third sentence is equivalent to this:
My view coincide with yours. Where are two negations here?
Conclusion: it seems to me negation is not a semantic, but a morphological feature of grammar.
