Exactly. Zaps are not equally accesibile for two reasons.
The senders. Poor people are left out. Their interactions would drop.
The receivers. People tend to zap more well known accounts, influencers, etc.
The halo effect. They are prevalidated and common people also desire validation from them. Senders send them zaps because they feel familiar and then sit there and imagine saylor looking at their zaps and thinking of them after his bot publishes an ai pic.
