Anything a best-selling author can do, anyone can do. And, with the possible exception of clasical Chinese, isn't writing simply a way of putting the spoken word into a permanent form?
I agree that the snippet you have quoted is ludicrous, but it seems that otherwise we must agree to disagree.
English grammar is a joy, when it isn't confusing. But who can help being confused when even the best linguists don't know whether the posessive 's is an inflection or a clitic.
And why should the word one take 's in the posessive when the rule is that pronouns do not have an apostrophe?
Confused?
