It will be like Star Trek and there will be no currency, this is so far in the future though, we will have automation and resources we can't even dream of.
The Star Trek model is based on "infinite energy" by the matter/antimatter power generation that made the "replicators" possible. If this is ever attainable, it will be centuries away.
It is also hierarchy military based, so I'm not sure how well it could last. Certainly the part of being contacted by alien civilizations played a role there.
In reality i doubt we will ever be contacted for
various reasons but if that ever occurred anything we say here changes.
To reach that level, we would need to spend enormous amounts in research and resources. Not before we treat our solar system like our playground, so called "Level II" on the
Kardashev scale.
For starters, the minuscule
LHC is unsuitable. We need planet orbit sized particle accelerators... We are going to have Mars inhabited and probably terraformed already before we manage to build one of these, and its corresponding dyson ring or whatever is needed to power it.
