There is basically nothing we could do worse than the current nazi capitalism in a well-made anarcho-humanist/communist civilisation. We all need to realize the sheer scale of misery and death that capital (and capitalism) spreads. Just, off the top of my head without even thinking, I can list like 10 horrible things we could fix with worldwide, fair, proper education and a systematically friendly power structure instead of the fuckass billionaire-controlled nation surveillance states we have right now.

worldwide racism
worldwide modern slavery (low-paying wage labor counts)
famine (also worldwide which is really fucked up)
homelessness (it shocks me we still haven't solved this)
queerphobia (and harrasment of most other minorities)
worldwide suicides and depression increasing (yes, really, we can solve this, and easily)
global warming and climate change (and the victims of it that we ignore)
you know, the 0,00001% richest people having more wealth than a large country??? Seriously Nvidia is worth OVER 5 TRILLION USD
fucking 90% of wars and genocides
Etc. Etc. Etc...
