1. All my friends/family/professional networks are based in the US. Do I need to convince all of them to move with me to the Netherlands?
2. I would need to uproot my children from their schooling and friends and move them to a foreign country.
3. I would have to get a job in NL--perhaps doable for me, but what if you don't have in-demand tech skills and don't already speak Dutch?
4. I would have to work in NL for five continuous years before being eligible for permanent residency.
These hurdles are indeed not totally insurmountable for some people, but to pretend like it's a viable option for anyone who wants to live in more functional cities is silly. Why can't we just try to make our cities better? Look around at which cities in the world are working better, and learn from them!
Why can't someone want to make where they already are better? Why should someone be expected to accept the status quo?
When you understand how quickly the Netherlands changed (it used to be just as car-centric at the US), you might change your view about what's possible: https://www.youtube.com/watch?v=bnFYOvcOn_E
