Supporters of the Saudi crown prince's ambitious project for opening the kingdom up to the world say these are teething troubles, inevitable when such a traditional culture is undergoing such huge changes.

California, which legalized recreational marijuana in 2018, has had similar teething troubles: In the first year of legalization, legal vendors in the state sold $500 million less worth of marijuana than in the year prior, when it was only permitted for medical use.

Whether this reflects teething troubles or a fundamental shift is unclear, and the changes have been welcomed in some quarters.

While the system could become more efficient in the coming months as teething troubles are smoothed, it is unlikely to become significantly less bureaucratic now that Britain has left the European Union’s customs union and single market.
