I don't think I like the idea of subscribing to and sharing block lists from individuals being a feature of nostr. It reminds me of the slow asphyxiation of dissenting voices on Mastodon when instances started sharing and building their own little echo chambers by sharing block and defederation lists.

Say relay runners used something like that for spam prevention, I'd be fine with that since I don't need to post to relays abusing it to replicate what killed the Fediverse for me, if some did. If a significant amount of relays were to start doing that, that'd kill nostr for me as well.

Nostr will probably see some growth in the coming years so we should expect influential people to land here at some point who might have bigger funding behind them who will try to grab some of these new eyeballs and bind them to their views, so they don't get exposed to the core nostr user groups and their narratives that contradict the clown world. It'll be a death by a thousand cuts and all these new nostr users won't even know what it's all about. Just another service with a fancy UX, perhaps even shitcoin "zapping" with some fancy on brand term.

Nostr should be the go to place for seekers of sovereignty and to me that stands in opposition to outsourcing the decision of what one gets to expose themselves to anyone else.
