It does not back up your claim at all.  If I have missed the adequate quote that backs up your claim please show me where it is. I am not above admitting I've made a mistake.  I've been up and down the page several times.  It's not there.  

That said, across languages, it's incredibly rare for a preposition to become a verb.  You have a big problem to overcome here if you want to call it language change rather than error.  This is especially the case, because if you point out to most people that it's "should have", they'll likely say something like, "Of course! My mistake."

Don't you mean "I of made a mistake"? /s
