I've heard about similar regulatory barriers especially in finance so this does not surprise me.

A long time ago I remember reading about banks that want to provide incentives for saving that amount to basically lottery tickets. The idea is that people aren't thrilled about a savings account that pays 2%, but if instead they offered a monthly 1 in 50 chance to get 100% return (same expected value, ignore compounding), people would like that a lot more. But this amounted to essentially a lottery and that's a state monopoly.
