What would be the lower tax/high salary comparable in Europe? London has remarkably similar salaries and super high cost of living. (I hear Berlin has a cost of living that's exploding and generally lower salaries.)

Blue card minimum salary included in the above link. Hard to know if you'd come out ahead given local cost of living, but you can also probably beat the blue card minimum for your salary in the Netherlands. I know a couple people who make > 100k euros (some contractors, some who have made it pretty far up at bigger companies.)
You are wrong about taxes. In the current tax year, 70k in one year in London would give you 4052 per month after tax. In NL, you would get 3668. That is no insignificant difference. You can verify this by using an online tax calculator.
I also don’t agree about the difference in cost of living. To dispel the most common trope, half a litre of beer in Amsterdam is at least 5EUR, and in London a pint (just over half a litre) is 5 pounds, about the same, given differences of currency and units. Eating out is strictly cheaper in London, and of higher quality. Some supermarket items are more expensive from my experience.
For a one bedroom flat not too far from say, The City or Old Street, you’re paying at least 1200, and maybe 1400 for something of higher quality.
On jobs, I have personally been hard pressed to find anything near the same variety and range of salaries in Amsterdam. There is a reason why so many Dutch programmers move abroad.

I definitely agree that there are more/interesting jobs for a lot of people in London, but I think that's changing. I think the other hard part for Dutch programmers is that the education system seems to be quite good, leading to a pretty deep talent market for a somewhat shallow hiring pool.
I do have one bit of terrible news: I think you've been overpaying for beers in Amsterdam. ;)
[0] One phenomena I've noticed is expats/immigrants tend to get better deals on housing because they have less cultural baggage about which areas are "nice" and can often see with clear eyes which areas are actually nice and which are actually bad.

For beers: I think you're looking at the "Grocery section", Beers are priced at 4 euros in the "Restauraunt" zone. I will, in actuality, buy you a delicious <4 euro beer at one of a few bars around our office. I don't know how many other consumer indices are backed by a personal guarantee.
At vending machines in train stations. When I was there, cheap Belgian beers were about EUR 2.50.
