I disagree.
Likes are useful as general nods of agreement that help people connect with others they don't know well and don't see in person. Remove that and you slow down the process of building bridges with new people.
If I were to write small talk everywhere, then my feed would be filled with noise. Not all zaps are visible on notes.
Likes are not dopamine drugs for sovereigns, they are indicators of general, positive non-verbal interactions that informs us about who may hold similar viewpoints.
