We require coverage of preexisting conditions in a bargain that involves coverage mandates (since struck down) and continuous coverage / enrollment periods. And health insurance is the primary payment gateway to a deeply distorted market that relies utterly on insurers to take payments, which is not something that is true of the housing market. I don't think I have too much of my identity invested in whether homeowners insurers need due process to not renew contracts, but I guess I'd argue the other side of that one. Either way: hard to see the privacy issue.
