I think everyone is trading anecdotal evidence, but in well over a decade of living in Europe and never bothering to make an EHIC, but sometimes falling ill when travelling in another EU country than my own, I have never been charged, and other travellers I know report that they have not been charged more often than not.
You would expect to be charged at an airport clinic, as this is a place that gets a lot of foreigners, so their billing is streamlined for it. Your treatment in a small town hospital that rarely sees foreigners would likely have been quite different.
I'm WHAT? I'm arguing for a change?
Is claiming that a status quo is unjust not wishing for change?
Your use of the term "currently" when referring to the ex-pats implies a short-term nature of the ex-pat status, which also makes them less than location-independent.
I don't see where you get that from. Merriam-Webster defines "currently" as simply " happening or existing now" with no connotation that it's a temporary thing. Many US citizens abroad have left the US for good (or have never lived there, but simply received US citizenship through ius sanguinis), and they now, as they vote, are living somewhere else.
With regard to the American Revolution, the colonists who pushed for a break with England supposedly wanted no taxation without representation. US citizens abroad must file US taxes, and denying them the right to vote would mean being taxed without representation.
Competition is a good thing. And even government monopolies shouldn't be protected forever.
Completely private industries have the possibility to keep their prices low for long enough to seriously threaten public transportation expansion plans or even existing infrastructure, and then raise their prices as soon as they no longer have to compete. In some cities, public transportation is answerable enough to the electorate that fare increases can be prevented.
I am aware that US citizens abroad can be subject to US taxes, and states may demand ownership of property for one to legally maintain voting rights there. However, I'm not sure that simply filing income taxes and keeping a property around would satisfy Obfuscant's demand that one be able to vote in a place only if one is subject to the overall laws there. The US simply has too old a tradition of people who have permanently left, and whose sole encounter with US authorities is income tax filing (on which most don't even pay anything anyway), but who still vote in US elections.
And you can explain why they should have any say in any election in a country they've chosen not to live in? I don't particularly care about those who think they should change where I live to be more like where they live.
I don't really feel the need to explain why. It's simply how things are and have been since well before I was born. It's you who is arguing for a change to a very old tradition in America (and many other developed nations) of absentee voting.
"If you care so little about a place that you cannot bother to live there, why should you be allowed to vote there?" Really, you remind me of those tiresome Slashbots in the early millennium who read a little too much Heinlein and urged a requirement of military service before one could have voting rights. They were so out of touch with reality they thought such a demand should be taken seriously.
Not legally. It's hard to claim residency in one state when you don't live there anymore.
Some states have very lax requirements for maintaining residence and voting rights there.
Neither are an example of location-independent people
You think that having US citizenship makes one somehow bound to the US? Not only are there people who have left the US for good but still vote (often so that they can try to make the US more like the country they currently enjoy living in). but there are also many thousands of people who hold US citizenship but have never lived a day in their life in the US. And with regard to out of state voting, it's entirely possible to be registered to vote in one state, and then spend the rest of one's life in another state.
