One member one vote doesn't seem very imaginative.
Compared to a dictator a focused team effort will have better results but a set of people who don't care or have an overly limited grasp of the topic won't do well. This probably doesn't matter to much if things are going well.
I fool around with the concept of department specific voting certificates with each component of the department written into its own "law" that one can vote yes/no and remove on. Each cert adding weight to the vote. People writing the rules are elected by the same mechanic. To activate a rule or board member it needs 55% "yes" to deactivate it needs 55% "no" and to remove it needs 65%.
One can participate in all departments and each certificate comes with a small pay raise.
Better anti-monopoly enforcement, better worker-rights regulations, better taxation schemes for redistribution, better healthcare etc. Even stuff you wouldn't think about like free college or good Singapore-style public housing reduces economic pressure on workers, which reduces companies' leverage.
Interesting, yes employee maintenance cost like healthcare and specially housing hurts the economy magnificently. That said, those things only make the dictatorship model more palatable. I want a system to compete with it and kill it.
The puzzle should be considered exciting. If I've learned one thing in life it is that it is easy to do better than a thousand people convinced it can't be done. Illusions of grandeur are useful.
As the article points out, there is a lack of a long term plan. If there is such a thing (however idiotic) you can promise specific taxes and regulations for things that get in the way and specific tax breaks and subsidies for projects complimenting it. It has to be clear and specific so that one can bank on it. NIMBY is fine, you get a reasonable bill for it.
Strong unions are another alternative to totalitarian control of companies. Not ideal, but there are plenty of examples throughout history.
I'm not claiming these alternatives are better or worse, I'm just pointing out that other systems are possible and already exist.
Fwiw, whenever my team has done democratic planning it has always led to bad outcomes
