That sounds like exactly the kind of addiction-reinforcing Skinner box nonsense that leads to influencers, parasocial relationships and a content economy, and all of the dark patterns of social media that the fediverse is designed to avoid.

People shouldn't be posting to get the endorphine rush from clicks or to satisfy metrics. They should post whatever they want, whenever they want. If you like what someone posts, you can follow their account, or better yet the hashtags they use. That should be sufficient.

Not having a like button seems like a good design choice TBH.

The issue with social media isn’t with encouraging or content creators, it is with how consumers are conditioned.
