The status quo advantages: a (relatively) stable and strong currency, meaning net importers are helped. Of course, that means our exporters are conversely harmed when selling to a ___location with a weaker currency (as our goods become more expensive). A vacation abroad is similar to a net import. You consume something in a foreign locale paid for with US currency.
The confusion I have is your argument of "that can't be the reserve currency advantage, because it's already true", which seems to ignore the (strong?_) probability that it's already true because of being the reserve currency.
I just suspect that I shouldn't really care what the reserve currency is. If anything, it probably has minor annoyances for Americans.
I meant that vacations for people who live in non-dollar places are cheap, goods are cheap. I recall that trips from Canada cost pretty much the same as from the US, taxes notwithstanding.
The main complaint I hear about goods is VAT and import duty where applicable.
