Imagine that economy that we know it today is not needed anymore, personal profit stimuli is just a page of a history and social and political life is just different from it's today version.
How then needs of people are solved, and on what would you spend your time and energy in that case? Did you see the crypto there, and if yes in what role?)
P.S. I know the Ideas of Karl Marks about post-komunism and not a fan of it)
There would be literally nothing of value to spend time on, aside from improvement of the self in a system in which there would be nothing that really matters, as everyone's needs are taken care of.
I don't know if you've ever thought about this but goals that end in something that is almost completely unreachable are the ultimate form of stimuli for a nation. Communism would result in stagnation for the entire human species, there would be no incentive to move forward and it would conclude with humanity dying on Earth with no ambitious spirit as sexual excess and gluttony would grip the overwhelming majority of the population, a massive stagnation of everything and ultimately nothing would matter. Magic gay space communism will never work since there's a need for people to want to work, and when the large portion of the community cannot get that dopamine rush off of exploring it won't work.
The struggle is literally the key component of human civilization. We would not be here without it.
- about struggling.
