I for one don’t think that regulations are always in opposition to efficiency. Where would we be with energy efficiency if not for regulations that penalise inefficiency? Living in the EU, I’m happy for the push for USB-C as a common charging port for now, that will make everyone’s daily life more efficient (not to mention help us produce less e-waste). How it’s going to be in the future, when something better than USB-C comes along remains to be seen.
