You keep painting the EU as acting like children when in reality all that is being described is the current arrangements for those countries that are not part of the EU and don't have an agreement with the EU. Arrangements that we in the UK currently apply to non EU countries without an EU agreement.If the EU decide to act like children and require UK citizens to obtain an international driver's license to drive there, then the UK would retaliate by requiring EU citizens to obtain same to drive here - but only EU citizens - visitors from the USA and elsewhere still wouldn't need one.
You appear to think that the benefits arising from EU membership should be the default position going forward. For UK commitments you think the default should be their removal.
If you are looking for childlike behavior, wanting all latest toys without appreciating that they need to be paid for, you might want to look a little closer to home,
