What learned so far:

you need to politically engage to fight for a life which is enjoyable

“You exchange real money at a booth, and in return you get tokens or fake currency that are only usable inside that ecosystem.”

To me that sounds like Reddit’s award system.

“Boosting posts or creators (opt-in)”

I hate this idea. I don’t want algorithms nor paid boosting to change the sorting of content. That’s one of the reasons I left Reddit.

Instead of introducing a complex internal currency or paid boosting, Fediverse instances could adopt a simple, transparent system inspired by Signal’s (the messenger) supporter badges.

Users voluntarily donate to their instance (one-time or recurring). In return, their profile gets a small, instance specific badge visible next to their avatar.

Badges are purely visual, they don’t have any influence on post visibility or sorting.

Edit:

I forgot to mention, that the badges are only visible for a certain time, like a month or so

edit end

I’m not saying, that this is the best solution, but to me this solution is fair, doesn’t interfere with the core values of the fediverse and still raises awareness of the importance of financial support.
