We have a number of tools at our disposal as drivers to minimise bad situations. Personally I think overuse of high-beams is more valid than under-use in quite a number of circumstances (and exceptionally bad in others).
Your comment implied that drivers who instinctively switch on their high beams to get a sense of a situation where they need more visual input are "jackwads" which I tried to highlight isn't the reason they're doing it.
Wanting to see more when you're driving a massive piece of machinery at decent speeds isn't something that makes you an outright asshole.
