As has been pointed out in many other comments implicitly and explicitly, the purpose of a set of address fields in an HTML form is not always to come up with a USPS delivery address.

Does that mean you shouldn't choose sane defaults or...?

Many other comments here have outlined the problems with what TFA appears to consider "sane defaults".

But sure, if you can do it right (e.g. "Put the country first"), then by all means do so!
