This doesn't seem this hard to me - everyone's different. If something works for you, good. It may not work for someone else. I don't see why everything has to be all one way, or all the other - some people may find minimalism works all the time, for some it may work in moderation, for some not at all.
Coming back from a serious injury this summer, I found I could only run barefoot without pain. So I did that for a while, and then obviously I did it too much, and my stride was still favoring one side, because I ended up fracturing the other foot. So I took time off for that, aand then started in very very minimal shoes which felt good for a while. Then I started gradually feeling like more support would be more comfortable, so I got slightly more shoe, and eventually I compromised into mainly wearing a reasonably lightweight shoe but with some support, sometimes running in very minimal shoes if my feet feel better in them (sometimes I put on shoes and it just feels like it's not working that day, and I wear something else, either less or more depending on how I feel), and the occasional day of some barefoot running for strength and balance, etc. This is what's working for me - and while I'll never go back to the orthotics which I feel caused my injury, I'm not comfortable doing large amounts of running without some degree of support either.
THe point is, I've found a combination of things that works for me. If orthotics work for someone else, then good. If all minimalism all the time works for another person, then good. I don't understand why it's everyone feels the need for everyone to be doing the exact same thing they are.
