The @bankless pod w/ @dwr.eth was incredibly enlightening for me when thinking about business on-chain. Specifically, Dan's focus on minimum decentralisation for maximum customer experience. 
Makes me think about developing an MVP style model for on-chain businesses, maybe 'MDP (Minimum Decentralised Product)'?

Thinking about Future Proof Business Models On-Chain

I should probably amend this to 'Sufficiently Decentralised Product'. 

Consumer Products/Businesses On-Chain should be Sufficiently Decentralised, to Maximise Customer Experience. 

Meaning, you should decentralise as much as possible until it starts to hurt customer experience.
