Yet Velo Vol was ready to throw dirt on my casket because of a couple of eggs. Protein. It's important.

My view is that sugar, starch - carbs generally - are fuel. Just fuel. If you're burning energy, you need fuel. If not, you don't. Fat is also fuel, but slower burning - though more energetic per gram. Important to remember that your brain only runs on glucose - part of why one feels so stupid when bonking.

First, when you're in Workout Mode, Erg or not, Zwift doesn't change resistance to match 'terrain'. It's either flat, or in Erg mode it adjusts the resistance with your cadence to match the specified power output for that section of the workout. So, you could be on Alpe du Zwift and it would seem flat, in Workout Mode.
SO, if you did the Ramp Test without Erg Mode, you'd just have to keep shifting gears to increase resistance, just like with a dumb trainer, but your trainer would be providing Zwift with your power output.
The other thing is that you can also change how closely the trainer tries to match the terrain. It's under "Settings" on Zwift. You have to be In Game, in a world. Click Menu, then Settings. Default for Trainer Difficulty = 50%, so it will mimic a 3% gradient when you're climbing a 6% gradient in the game. I generally run it at 100%, since I'm trying to mimic riding in the real world, but if I were to try Alpe du Zwift, I'd probably cut it to 50% the first time.
Two things about Trainer Difficulty - First, even set to 0%, so everything seems flat, your speed In Game is STILL determined by power output, gradient, weight, and aero profile, so if at 0% Trainer Difficulty on a 15% gradient, you might be spinning easy, putting out 150W, and feeling like you're on the flat, but you'll probably be going 2 mph.
Second, on descents, Zwift only mimics HALF of the descending gradient. So a 6% descent is really only 3%, at 100% Trainer Difficulty, and at 50% it would only be 1.5%.

Then, of course, a bunch of them died in WW1.

True, except you can make your own carbs from fat and protein and the brain only requires something like 30% glucose in the energy mix after a few days of adaptation to carbohydrate restriction. Technically, therefore, you can live on very little carbohydrate, like Shackleton's men, who survived in good health for months on a steady diet of seals and birds and then had the energy to make an arduous ocean crossing in an open boat and trek over the snow-covered spine of an island.
Prolly.

I just did a Zwift workout on the London Loop and just peeked at the leader board. The KOM? I mean, come on. I'm sure that the rider is very strong, but his 2016 ride was 18 minutes and change and his average power for the duration is indicated to be 546w.

I would think that, in 2016, this was wildly enthusiastic zPower estimate on a dumb trainer. Whatever the case, 18min at 550w just isn't on this side of reality. I mean, if you work backwards from Wiggins' hour record (was that 440w?), you're not getting those kinds of ~20min figures.

It's possible. That is from Zwift. And when I ride with my friends on Zwift, I am often dropped and once dropped, I can never get back. On the road, I have no problems keeping up with said friends and have no trouble dropping most (if not all) of them on the longer hills. That said, I am not "training" for anything other than fun rides. I don't want or need a power meter for my goals.

I crush my friends' souls on almost every significant hill we have. That's good enough for me. They usually catch me on the way down because (a) gravity and (b) I descend with caution.

I do remember early on, seeing some people I ride with IRL, on Zwift with just amazing power numbers, knowing there was just no way. And yes, it was dumb trainers and Zwift's interpretation of power.
