I agree, but people should be free to do what they want with their Hive Power. They can generate passive income by delegating to different curation trails, just as they can by staking HBD, so I would be careful here.
Of course, manual curation of content is very time-consuming if you don't want to be a comment troll. There is a need to balance use between everything Hive offers. The first step towards this is engagement and communication with others.
