I think you need to differentiate. Some issues can't be optimized by the people facing them daily, because game theory forbids them. Issues involving coordinated action are basically unsolvable bottom up.

I think history disagrees with that. With deregulation and incentive and because how the resource pool in human civilization according to Pareto distributions. You can have a individual coordinate most things bottom up if you let them. Like people thought private space flight was impossible, but it ended up being more impossible from a top down process than a bottoms up on via elon musk.
