Oh, I guess this is the video 4v4l0n42 promised us.
Let's analyze some of his mistakes.
1) desired results
Findeton was wrong when he said "There's no scientific theory on whether you should use nuclear power plants or solar panels.".
Yes you can and I'll tell you how. First you
decide the desired results...
Well, that's exactly what findeton was claiming is out of the scientific method. Science doesn't give you desired results. Presenting Findeton argumentation cut and out of context makes him look right, but nothing else.
2) maximizing the
well being of everybody
You cannot maximize the "well being" of everybody because the "well being" is subjective to each individual. You cannot even define a fungible unit (like watts, newtons, or grams) for the function you're supposed to maximize. You have no means to measure that "function".
You cannot define well being scientifically.
Even if you had all that and the perfect plan you need to motivate people to work on your plan (or wait for the singularity robot that will make it for you).
3) simulation of people's decisions
How do you simulate the people wants and cultural developments?
4) free market requires growth
No. This is false. Only our current monetary system requires growth because it is designed as a ponzi scheme of debt.
With sound money like gold, you would have business cycles that stop the unsustainable growth that capital-money demands in the form of interest. Well, with fiat currencies you have them too but commercial and central banks (and governments) try to stop deflation and just postpone it by printing, making the crises worse.
If they keep on postponing deflation with the current crises, we will end up with hyperinflation for the dollar (with catastrophic consequences for the entire world), maybe it is already unavoidable.
But you don't need capital-money in a free market.
You can have money free of interest like ripple or freicoin.
