It's a problem because once the state gets revenue from a vice, they have an incentive to promote that vice. This is particularly common with gambling, where you have state propaganda (billboards, TV and radio ads, etc) encouraging people to gamble, even portraying gambling as some sort of way to invest your money.

Gambling is also sometimes considered a tax on the poor. But my point is it can be easier to levy a vice tax than raise income taxes for example.

AND with vices people will do them regardless so maybe some social good is better than no good coming from it.
