We have to agree "money bad" before making a plan to move beyond it.
Yes, but that's not the thing you said that I disagree with:
humanity absolutely has the ability to coordinate action without money at least as well (if not better) than how it is now
Replace "ability" with "potential" and I agree with you, but as written this is misleading. It assumes the planning has concluded, and a new system is ready to be implemented. This is not the case.
there is a plan that I did mention, socialism
Either "socialism" refers specifically to the USSR's plan, in which case we've seen that fall to corruption, or it refers to a more general concept, in which case that's more of an ideology than a plan. At best it's a general roadmap, but it's not policy by a mile.
Socialism is not immune to corruption. No matter what system you use, people will find the loopholes and vulnerabilities and blind spots. You're just trading billionaires for bureaucrats. Even in a direct democracy, they'll start podcasts to sway public opinion. They'll steal from library economies, they'll loaf in spontaneous mutualism.
You cannot eliminate this element, you can only change its form.
