Predatory advertising, gambling, they both prey on people.
Cards on the table, I think both advertising and gambling should be heavily controlled.
Many developed countries are struggling with birth rates for example. Should that be regulated? It is harming countries much more than gambling could ever have. The whole right-wing resurgence happening across western democracies is a direct consequence of lower birth rates demanding offshoring and immigration.
The kind of folks who will take that offer are more likely to be terrible parents.
Anyway, my point, that you seem to have completely missed, is that some rules that Americans would reflexively dismiss with a thought-terminating cliche like "nanny state" are in fact necessary. You wouldn't want the road to be a free for all, would you? Well, I don't want psychological warfare to be legal and used to trick my neighbor into losing vast sums of money to online platforms. Poor, addicted citizens make the country worse for everyone.
Also, "But the person that sells them the poison has to make sure they are of sound mind" made me laugh. When has it ever been in the business owner's interest to vet his clients? Legalize fent and in a year, half the superbowl ads will be selling you drugs in rainbowy attention-grabbing displays of decadence.
The bit about poor addicted citizens (if it actually is the cause,instead of welfare and similar things), it sounds like your priority is improving the economy despite its effects on people's rights?
> When has it ever been in the business owner's interest to vet his clients?
When not doing so could mean serious consequences, like capital punishment or life in prison.
Someone high on heroin or going through withdrawal from heroin is not of sound mind.
