I don't understand this part. Maybe I'm misunderstanding 'akimbo' but what I see in google image search doesn't seem useful to me: https://www.google.com/search?tbm=isch&q=elbows+akimbo

I actually keep my hands in more of the "secret service stance" rather than on my hips so that if I'm pushed suddenly I'm more likely to have my arms available for balance, or grabbing/pushing people so I don't fall. Having your arms at your side is not good when you get pushed very suddenly because usually your arms get pinned to your sides and then they're completely useless.
When things get really tight, I put my hands together in front of my chest (up by the sternum) and put my elbows against my sides. That forms a triangle and protects from the front and sides. Again, the hands are up and available so that they don't get pinned when I need them most.
In my experience, elbows crossed in front of your chest will give you a little bit of extra breathing room, but even that doesn't do much.
Even as a 130lbs guy, it's surprisingly easy to make a bubble if you just throw yourself at people back-first, and keep moving around roughly in a circle. Flailing your limbs also helps.
Or at least it worked when I was at a hugely packed Guns'n'Roses concert at a festival a few years ago.
The New Yorker and The Atlantic can be interesting, but with the rise of the web and not so much empty time to try to fill, one sees how they expand a little bit of information to fill all of the empty space between the ads.
