For me, it's not the salt on the paint and all the areas that can be visibly washed that bothers me, it's the salt that gets itself into inaccessible areas of control arms, chassis rails, bodywork, suspension, brakes, crevasses, subframe, drain holes and so on! I spent over a year(!) with my car stripped in the garage, meticulously sealing and protecting all these areas and I still don't use it in salty weather! In my mind that was just belt and braces.
Pressure washing the car will also likely just force salty water further into areas you can't see and unless you're careful, wet washing the car regularly naturally forces water into areas that pool and can cause issues of their own.
That said, as a daily drive which has to be used in these conditions, I guess you're right in that regular washing has to be better than leaving it all to dwell! Besides you shouldn't listen to me as my morals are extreme, I blow dry my Z!
