Sure, but at that point you're having to buy a car (which is much harder as a young person - car prices have gone up, insurance has gone up faster, the driving test is harder than it was and lessons cost more...), you'll need somewhere to park it which adds to your housing costs, you still can't go drinking, and in general you're cut off from a lot of what young people are doing.
Even tiny UK towns have excellent walkable mainstreets and are small enough to walk from field to field on the other end in no time. It is a far cry from the american obligatory car experience where it might be a 2 hour walk to your nearest grocery store even in a city suburb.
