Eh, might as well LARP a bit. Someone somewhere might laugh at this in some reactionary rat's nest elsewhere on the internet, but to hell with them.
Stating my ideal society is a bit of a cop-out, it's more interesting to talk of the transitional period i.e. of the socialist society that should exist between the revolution and the communist society.
Number one priority, of course, ensure everyone has at least the minimum necessities not just for living, but for living with dignity. This obviously would require economic optimization. Leading me to…
Collectivization of the means of production is a given. But administration at lower levels, like co-ops, are a risky throwback to capitalism, and administration at high levels, like nationalization, well, see 20th century for an example. I'm growing increasingly convinced that automating the economy is a necessity for socialism and thus communism. And I don't mean automating all economic activities, I mean automating the economy itself, as a system. Cockshott and others inspired by the Soviet cyberneticians are my biggest hope on that front. As the system becomes more refined, the need for currency as a mediating agent will decrease; it might virtually disappear in the primary and secondary sectors and remain just as a simple scarcity regulator for individual consumers.
Other than this "decentralized planning", it's vital to keep industrial automation growing. As Marx said, industrialization is the only thing that truly brings wealth, as it multiplies the value that can be created, thus extensive or full automatization is necessary for a given commodity to ever reach post-scarcity, and I'm starting to think that the infamous "withering away of the State" can only happen when post-scarcity in the entire economy is reached, by virtue of it making the State more or less redundant.
While we do have a State tho, it has to be treated like the beast it is and be kept in a tight leash. The legislative branch is abolished, and any citizen has the power to participate in parliamentary practice at all levels, which will no doubt require telecom to accomodate everyone. Executive offices (which include a body to organize the "people's legislative") are short term, as in 1 or 2 years, and occupants are determined by either sortition or direct democracy, depending on the job, and they all have to pass competence tests devised by a conference of all public universities. As for the judiciary, I'm torn. It requires highly specialized knowledge, and it's particularly important that it relies on merit instead of election or sortition. Possibly an arrangement involving the university conferences choosing candidates for judge spots.
On more ambitious scales, remodeling of cities, beginning with transport. Virtually all modern cities have been built to accomodate cars not humans. The amount of space dedicated to vehicles is preposterous. In fact, cars themselves are preposterous in this day and age, as I don't need a 1.5 ton metal behemoth to transport my 70 kg self, or even my 200+ kg immediate family. The vast majority of the energy from the combustion of fuel isn't transporting me, it's transporting the transportation itself, and that same unnecessary mass makes for horribly dangerous crashes. It's insane. Almost all transportation should be both public and automatized, perhaps with a system analogous to that which controls the economy, and vehicles are as small and light as possible, which combined with automatized driving, makes accidents both rare and non-threatening. Bigger vehicles are available for people carrying luggage or cargo or such. Product transportation might be the part that requires human drivers. Needless to say, transportation between cities should be completely by rail (or a successor technology) if possible. Ultimate goal would be to dismantle highways.
