Absolutely hate BankID, making it too easy to integrate has resulted in businesses and the government requiring it in places where it's totally unnecessary.
I live overseas, don't have a Nordic bank account. Now when I'm occasionally visiting, I can't buy alcohol because the website requires me to prove my age with BankID.
This, as opposed to most of Europe where you can just have alcohol delivered without anybody asking you for ID at any point. I'd be happy to show an ID at the point of collection/delivery, but buying beer shouldn't require strong KYC.
You are misrepresenting this slightly in my opinion.
Yes, we have strong laws around alcohol sales in Sweden that try to limit damage to society from excessive alcohol consumption while bringing in tax that can be used for state services instead of going to corporations.
However!
We have a well-run state monopoly (Systembolaget) that sells alcoholic beverages at reasonably good prices, with a wide selection and friendly knowledgeable staff. You don’t need BankID to shop at any of their physical stores which are spread all across the country. If they think you might be under 20 you will need to show physical ID, passport is fine.
Any restaurant or bar that sells alcohol will happily sell to you, unless you are underage.
Low-grade alcoholic beverages (<=3.5%), including many beers, can be bought in any grocery store.
Sweden is one of the most legally restrictive European countries when it comes to buying alcohol though. So no surprise that it's harder here in that regard. I'd be very surprised if you didn't need to use BankID to buy alcohol online. I'm surprised you can buy online at all.
