Unironically ban all gambling
You can get scratch offs at any Finnish supermarket and kiosk (think 7/11 but wayyyyyyy smaller and with a way smaller selection) :shrug-outta-hecks:
All gambling (with the exception of dubiously legal foreign online gambling) over here is run by a government-owned company
Denmark also have a government-owned gambling company that does lotto, scratch-offs and sports betting. They’re present at every kiosk and supermarket and also run a sizable online casino. They used to have a monopoly on gambling but due to the EU’s liberal orthodoxy the “gambling market” was “liberalised” opening up for predatory betting companies to suck money out of poor people.
