It parses easier, but it's still doing extra work to negate the 'needs'.

doesn't need privileges > needs zero privileges > needs no privileges

"No" here doesn't negate needs. It is part of a subordinate clause "no privileges". Substitute with "nothing" (literally, no thing) for the same parse.

		Agree. `"Give me a 4 apples." "Give me a 999 apples." "Give me a 0 apples."` The last one doesn't say "do not give me apples" and it surely doesn't say "do not give me a zero apples".
