For me we are not abusing the decentralization technology rather we are maximizing the benefits and advantage it may bring to us and until now massive development are being introduced to public. In due time decentralized technology will play a major rule in more advance technology.
Sorry to OP, though isn't what you've state is much more of personal advantages? In another area, Isn't that some uses the decentralization in (morally) illegal ways. Though, we can't deny the improvement of the system but I think in some areas we are abusing the these "Decentralization". Though, I'm not quite sure about the "Decentralized" will play major "Role?", What role or "Rule" specifically? As far as I know, Some or most of the countries are not supporting the decentralize idea in a system.
