Apparently not, as you said "Sadly that's not going to happen, and I knew this going in"
Like I said, if you truly require 325 miles in 20 years (whether that's an actual requirement, or just an expectation, is a whole different matter), you should have bought a vehicle with more range to start, or if the future accounting stuff is too difficult, then a car like the e-Tron where the manufacturer (supposedly) hides some of the capacity from you to give you a more consistent lifetime capacity.
Unfortunately for you, that's simply how batteries work. They degrade over time, and you need to account for that. You must really hate smartphone and laptop batteries that degrade much faster. Do you have similar expectations for other things you buy? That they will not degrade at all? And yes, I know you will throw out another comparison to your 20-yeard old Benz, but that's somewhat of an apples to oranges comparison. It would be kind of like I bought a new ICE car and was "shocked" to find that the car would not function properly if I didn't go through the process of changing the oil every 5000 miles or so. Well my electric car doesn't have that extra fee involved! My brand new Benz was working fine when I bought it, and I expect (require!) it to continue to operate for 20 years without having to remove and replace fluids in it periodically!
I never said it was an hour long experience, and while standing in the freezing cold is not pleasant, for me it was more about time and money. While the actual pumping process might take 5 minutes, driving out of my way to go to the gas station every week or two, sometimes waiting in line for a pump to open up, and then navigating back onto the way home adds up...week after week. And compared to what I pay in electricity, the additional time and money I spent on this adds up. Over the course of a year, just counting normal everyday driving, I estimate that I spent about 8 hours doing this. Sure, it's spread out over a year, but it's still a hassle. So when I hear someone complain that they have to add 30 extra minutes (if that) to a trip they take two or three times a year, I just have to wonder...
Why are you talking 0 to 100%? Do you actually drive your EV that way? Is that how you charge your phone? You wait until it's right down to 0% and then charge it all the way to 100% before turning it on again, and sit there and watch it the whole time? If this is how you think an EV is charged, you're simply doing it wrong.
I am not saying that in your particular experience that this is not true, although I question whether the perfect storm of having unplanned, emergency (immediate action) and remote (no Superchargers) is reality, or just an imagined scenario. At any rate, yes, unplanned things happen. It's a far stretch to make the statement that Teslas are not up to it, even if the likelihood is especially rare. I suppose if I lived out in the middle of nowhere 5 hours from the nearest hospital (if there even is such a place), then that person might have a case. Otherwise, what's so hard about keeping your car charged to a level capable of reaching the nearest Supercharger in 2021? For a vast majority of the population, this is easily done.
Well, I suspect you are over-complicating your description of "owner management" of the battery. I'm not even sure what you mean by that. You set a charge limit to "daily" most of the time, and "trip" when you are on a trip. You plug the car in when it's parked. You use the nav system when routing to a far away destination and let the car suggest charging stops. Sorry if I've missed something, but there is not really anything too difficult about that.
