We have different styles. I don't know where you live, but in the densly populated northeast, half the things you described are either illegal or perpendicular to LNT.
I won't dig holes for a fire, let it burn to coals, make a huge fire big enough to warm a group, or build a fire off-trail. All of those are bad news, and some of them have a legitimate chance of starting a forest fire if not managed.
I'm plenty good at making fires- we set one up every time our campus does a trip, but all in campground fire pits.
I got the Vargo because I knew the wood use was somewhere between one and three handfuls of twigs, with easily scattered ashes and no holes or rock circles. So, I've gotta stay thinking small.
If you know what you're doing, do your thing, man! But it won't fly next to the AT where I live :)
Thanks for the videos though. I'll practice that for emergencies.
