How exactly do you define decentralised solutions though?
Aren't coops like #JamCoop and @mirlo, or #SelfHosted sites just that? (Admittedly without federation)
#DIY, #artisanal, #coop and #OpenSource solutions usually won't be able to compete with big businesses when it comes to price and/or convenience, just like your community supported farm can't compete with Aldi.
It's really down to you as consumer to decide what is more important to you, convenience or doing what's right.
