Excuse me? Policy discussions are supposed to ignore any other
constraints (like the technical feasibility of something)?

I too would love to give everyone permanent, portable addresses. But I
also know we currently do not have technology that can do this. So I
don't support something that I'd like, precisely because I have real
worries that it will cause big problems down the road.

AFAIK, I have never claimed there isn't a problem here. The issue is
what is a reasonable solution. Just saying that we should do something
anyway, and hope that something happens that solves the technical
concerns that are sure to come later, doesn't strike me as good
policy.
