Usually this makes people go for very simple solutions without thinking properly what are the right data structures and algorithms for the problem at hand.

I rather write proper designed code and write the tests afterwards, before delivering the code.

True, however the solution is ok since passing the test is the only quality you need.

If not, write a new test, make it pass. The naive implementation can be substituted with a different one easily since the tests guarantee correctness.

Generally though, since the "third leg" of TDD is refactoring, this ensures that the proper structures are going to be used in place as soon as they are actually needed.

Have you ever tried to apply that in a big enterprise?
