Investing is gambling, they want to ensure you have the means, experience and nounce to gamble.
The risk limitation is for them, if you lost money and could claim to not be aware of the risks and that they took no steps to check you out... you could sue them in the future for far more than the fees will pocket them.
So they have to do it. It's not just a government required thing (it is that too), it's self-preservation by them. And they hope it's your own self-preservation too.
It is due diligence and risk limitation.
