You are correct. The vast majority of things in one's life are just as worthy of your time (if not more worthy) when the people providing these things are motivated by financial return. And yes, this principle applies to the quality of online content as well.

However I do not use Nostr to view that sort of content; I use Nostr to talk with people. I want to try to understand every belief and learn every relevant perspective. These matters of perspective are the exception to the rule. Motivations of possible financial return undermine the authenticity of the conversation and make it less worthy of a person's time.

The value of things like conversation and friendship are not things that can be objectively measured by the person receiving them. I believe Nostr should be partially unpleasant. I want to interact with the jerks. If I didn't believe in the importance of treating jerks with respect and fairness then I wouldn't have choosen the username "Scoundrel" to use when presenting and defending my beliefs.
