They are optimising different things and the GDP for them is just a means to an end. They are trying to achieve objectives like: healthcare for all, certain minimum standards of living and safe neighbourhoods everywhere. It's natural that if you don't optimise for GDP then GDP will probably not be maximised.
What our objective function should be is of course a very deep and interesting question. We don't talk about it enough. Most people think about solution first like: socialism, liberalism, sharia law, biblical law etc...

They're not unrelated though.
Suppose that at a 30% tax rate you long-term end up with a GDP per capita of $50,000, whereas at 20% it would be $80,000. Then in the first case you get $15,000 per capita to provide healthcare and things, whereas in the second case it's $16,000.
There is a point where that stops working. If a 15% tax rate would get you a GDP per capita of $100,000, 15% of $100k isn't more than 20% of $80k. Then whether the extra GDP is worth having lower government revenue becomes a more complicated question. But if the tax rate is too high, it isn't even a trade off, the higher rate is just a net loss to everyone.
I get the idea that small fractions of bigger pies can be more than a big fraction of a small pie. And I can assure you that Scandinavians are well aware of tax revenue optimisation.
I will even say that it is very likely that they are already near the optimum for their country. The reason is simply that if every time you increase taxes and notice revenue goes down, you will naturally reverse it. Society moves through incremental changes.

That isn't necessarily how it works.
Suppose you increase taxes and revenue goes up by 5%, but growth goes down. Now in ten years your economy has grown by 2.5%/year instead of 3.5%/year or more, so your tax base is >10% lower than it would have been in the alternative but at no point is is less than it was the year before.
