The doing away with luxury and eradication of a wage system Christ-centered? Really?
No, these are Marxist ideas. But worked out into an anarchist framework instead of communist (no central Gov't).
Sure, really: as long as it is voluntary and not controlled by the state and other coercive mechanisms.
This is not to say that a wage system,for instance, is immoral. It is not condemned in the Scriptures, which assumes wages, and demands just wages.
The Prophets of Israel, the Gospels, and the Fathers of the Church all condemn luxury, and, for that matter, covetousness and usury; which would certainly cut the legs off of modern captialism, powered as it is by advertising and consumer credit.
A free society which respects private property (which Day also supported) will also respect a diversity which makes room for distributism, communitarianism and even monasticism. Freedom would mean you can go and come with that, as you judge best.
