US didn’t really ban it because they didn’t like it. While there was a women’s group protesting against the alcoholism in the country, I don’t think it would have had any traction were it not for the anti union push.
Saloons were a great meetup spot to make unions. Everyone from work was already there. If companies could make saloons illegal, it would make it harder to make unions. But there was a problem. The US got a lot of its tax revenue from alcohol taxes.
So they pitched the idea of replacing alcohol tax with income tax, making the budget balance (in fact much improve!). So it got passed to benefit the US government budget, and help the union situation for companies.
It was not prohibited for long. As you stated, it quickly went awry. But it didn’t matter. The US government now gets its income tax, plus alcohol tax now. Saloons became less popular since they were gone long enough for habits to change.
You overestimate how much nature we step in on a given day. It’s usually basically cement everywhere
