This present a false dichotomy of extremes: shitty code and hopelessly overly complicated intended to address all manner of eventualities that never materialize.

Both extremes are awful choices IMO. If the code you are writing is truly unlikely to be extended and adapted then it may be fair to relax your requirements for code quality. As for most things I'd say that applying some discretion to your actual context is more valuable than blanket approaches of embracing bad code.

Code can be good without taking forever and without being over-designed. On the other hand the accumulated effects of shitty code upon more shitty code is unlikely to be a net positive.

Well-designed code can be simple.
