Wili,
I agree that what you call psycho-social dynamics is a very important factor in what both policy makers and scientists are prepared to consider with regard to ASLR. Unfortunately, by the time that decision makers are likely to accept the reality of this risk, it will likely be too late to stop much of the potential ASLR, and if so then our only options will be either coastal defense measures or retreat.
Best,
