Say what you will, but the countries with a good balance of socialist and capitalist policies are still on the top of every list, from happiness to life expectancy, to income equality to health to education, etc.
You can say what you want about Canada and Sweden, but when compared to the US' far more "anarchist" approach, both have far longer life spans and higher rates of health than the US does.
As you use very ambiguous terms like Bookchinite, and confederalist which are open to massive amounts of interpretation, it's not really clear what you are proposing (government is a form of confederation, after all). But I suppose you are hinting at being a Libertarian Socialist. It's a view which I am very sympathetic to, but one in which the upheaval needed to implement would end us up back at some form of fascism, similar to the previous attempts at communism. I would love to see such a system someday, but I think the only way it could ever come about is by starting from social democracy and gradually working towards it. It could likely take centuries.
Social democracy is the best system we have managed to date by just about any yardstick we have for measurement. That's not to say it's perfect, I can imagine many types of organizational systems which could be considered far superior should we actually be able to implement them correctly, but unfortunatley human nature is a massive blocking point to so many things, and the tendency is always towards some form of fascism if things become unstable. So IMO, we have to first get as much of the world onto the "Scandanavian model" of stable social democracy with good rule of law, and then work from that point of stability to something even better (I'm a fan of UBI personally as it's far easier to implement than any sort of system which gets rid of property rights and achieves much the same thing when widely implemented).
