Knowing that a post reached 121 individuals is more valuable than <$0.01 with confirmed reach of only 1.

Not all value is monetary in a social setting. Both small zaps and likes are barely engagement, but they are engagement. I don't intend to ever deprive my people from having a way to interact with my content without a financial or time cost. If they aren't stopping to comment, my words weren't valuable enough to warrant it, and I don't expect payment in lieu of what equates to an upvote or mark of approval. Zaps are amazing, and a huge part of why I love Nostr, but they are not the same as a like, and there will be many who will not use them.
