If you don't feel strong emotional attachment to some particular property, I'm not sure I can explain it to you. There is no monetary value that can replace the living room where you watched your kid take their first walk, or the field where your grandparents are buried, if you happen to be that kind of person.
An analogy: why not make taxes voluntary? (Eminent domain is conceptually most similar to taxation, after all.) Surely after you explain that it's to the public good, you won't have any holdouts, right?
I understand emotional attachment to property. I also understand that nothing is permanent and it may be necessary to let go.
Since I was a child, family moved and sold previously used estate/flats more than once. Yes, there are memories and my grandparents built and lived there. Now other people build and live there. Life goes on.
We are not talking about somebody persuading you to sell your property to satisfy their fancy. It is a cause that will have positive effects on the region and the country.
And you personally, meanwhile, get a free chance to move and find an even better spot that doesn't have the shortcomings of the previous one. I recall that's sort of how USA started.
Framing emotional attachment as an overriding motive and purpose strikes me as an excuse for complacency, aversion to change, laziness.
