Especially given the fact that we have, in theory, the order of magnitude of computing power necessary to calculate an economy. But to implement it well would certainly be the most complex and titanic project in the history of computing, and even then it might fail for some unknown reason.

Worse yet, a failure where the wrong people accumulate wealth will just look like planned corruption to the masses. Sadly one reason why central planning often is accompanied by censorship

It has often occured to me that one of the rationale to start a colony in Mars is that wealth (at least on Earth) is mainly distributed among the wrong people, which is why so many short-sighted decisions have been made collectively by us who dominate the planet. And real innovations and progressive things are super rare. And they are often accompanied by (unnecessary) tragedies or sufferings that don't have to be that way. Theatres and facades are the norms.

But I now have come to the realisation that wrong is perhaps only in the eye of the beholder.

And there will always be censorship in a society as long as you look hard enough for it. Probably a feature not a bug though.

Maybe it just demonstrates this is the best we get collectively with neural circuitries like ours.

I have lamented that a model of censorship is equivalent to free information consistently cherry-picked. In terms of censoring misinformation, there is potential benefit. It needs a system of public trust, however

Yes. You would either need massive censorship or insane levels of technical transparency. In both ways it's a huge technical challenge.
