"Ahhhh, yes. All honest people I know have at least 9 fake driving licences"
To be fair, there was a time when I had four (non-fake) driver's licences. (UK, Jamaica, Barbados, and Florida) due to the inadvisability of displaying a Jamaican license in, well, the other three, the inadvisability of displaying a Florida (or any American) license in the UK or Barbados, and the extreme inadvisability of displaying a Barbados license in Jamaica. (You do _not_ want to be identified as a Bajan, particularly a pale Bajan, in Jamaica. Nope.) I could have just used the UK license, but that one was also the one which was almost expired at the time I got the Florida license and I really wasn't flying back across the Atlantic to renew it.
Having multiple driver's licenses is proof of nothing more than wanting to be able to drive in multiple territories with minimal hassle.
That said, nine licenses is rather overdoing things a little. And even one fake license is... questionable.
