There has never been any risk of losing free movement until a couple of years ago. We've had it all our lives. I have been extremely risk averse in my life. I am being punished by my fellow citizens for not taking risks. My fellow citizens, of a country that you are so willing to defend, are pushing me towards death.
No, there's always been some risk of losing free movement. In the same way, there's always a risk of recession or economic hardship, which is why people ought to save money and think about how they'll cope if the worst happens.
Setting yourself up to retire on the absolute minimum you can afford, and wanting to move abroad to a country in which you weren't born and aren't a citizen doesn't seem risk averse to me. It seems
incredibly risky, particularly when if it doesn't go to plan you'll end up hating work, hating the country you live in, hating the people who live there with you, etc etc.
You'll probably be able to work in the Netherlands if you like - perhaps there'll be requirements for you to have certain skills. Whether you'll be able to retire there having not paid (any?) tax to maintain or build the super infrastructure they have is another question.
Brexit is not great and I lament it (and the way it is happening), but I don't think people voted to "push you towards death" or, conversely, to punish me for some unseen sin.
The simple fact is, voters chose to Leave, and that's that. I don't like it, but I do realise my "side" lost and I'm past moaning about it now. Brexit has illustated to me though that it's not just a lot of Leavers who have unrealistic expectations from life.
I'm afraid I have very little sympathy.
