Big name publishers may be essential for great _looking_ articles.
A great article, though is usually not a matter of beauty.
Actually, we have been living in a very similar situation since home power-tools became available. There is so much stuff you can make for yourself literally in minutes.
People in the eastern bloc actually lived a lot like that. Food, electricity and housing (and a scarce collection of consumer goods) were provided by the state, a lot of the rest was made at home. They used to get blueprints for clothes they wanted and produce them themselves.
It just gets problematic as long as there is any discernable difference between the self-made product and a commercial alternative. Any small defect in the self-made product will lead to a percieved lack of value.
Otherwise, the economy will get more intellectual property based, I guess.
BTW, power and water are already provided by the state in some western countrys. Food and land though, not so much.
