The idea of basic income is that it provides the basic human rights in a more libertarian manner (instead of the government providing services, the government gives you money). So, if someone doesn't have enough money to buy food, they won't starve to death and the facilitation of this human right is done via the market in basic income. I don't think a basic income set to provide basic human rights is going to create any sort of drug-user like dependency on the government.

Regarding population, when you have more people you get more money.

What are these Scandinavian cultural norms?
