I don't understand your point.

Even if HN used oAuth - even if they required oAuth - ultimately oAuth, oAuth as implemented on most sites is just a thin layer over email so you don't have to make another account.

The problem doesn't require blockchain as a solution. What would the website administrator gain from accepting a blockchain login? People would create accounts but you have no way of contacting them since you have no email. Clearly the kinds of sites you're describing wouldn't accept that.

OK so you associate an email with your blockchain login - so now it's the same as the status quo. What's the point?
