(Not sure if this is what you mean, but) Blocking paywalls wouldn't make HN better. It would make it much worse, because it would exclude many good articles. That's why the rule is to allow paywalls that have workarounds, i.e. that the community can still read.
If anyone has a suggestion that would actually make the situation better, I'd love to hear it, because the current situation sucks, and has sucked for at least 10 years. It just sucks less than the alternatives we know of.
