This is a foolish requirement.

VERY foolish.
Those people who won't/can't provide those requirements should merely avoid such a casino.
Yes, but the problem is that they are asking these requirements when you already deposited some money or won some bets, and want to cash-out.
I wonder if that requirement is mentioned in the TOS. Otherwise, how will you avoid it if you have no way to know it on beforehand?
