The society is not separate from "those people". Indeed, given the results of referendums, it would seem that the society is in fact mostly those people. So, who should be imposing guardrails on them, exactly, and how do they justify it in a democracy?
Most people know that they could use a little help from society. After all, people voted for gambling bans in the first places. What changed is we went through a libertarian phase as a country where we promoted individual choice as an end in itself and demonized any attempts at social regulation of choices. As we see the effects of that, I don’t think it’s
impossible to imagine getting the pendulum to swing back at least partially so people might decide gambling bans were a good idea after all.
