The answer is to reduce the centralization of jobs and other factors that cause everyone to want to live in Amsterdam, e.g. building out Lelystad or Buitenveldert. To a certain extent, COVID and WFH has started doing that.
I lived in Amsterdam in 1999 and house prices there seemed quite reasonable to me compared to Paris where I was coming from, but of course many things may have changed in two decades.
You're sort of "begging the question" here.

Obviously I'm not against that happening but it's not either-or.

Oh, you have no idea. It was hard to even get the owners to get back to you, because they'd already accepted an offer; and I was being asked for 1,500 EUR - 1,650 EUR/month for a bedroom+living room apartment. And while that wasn't in Diemen or Bijlmer, they weren't in posh super-central locations.
