I am not a minimalist. When in full mode for wildlife and nature, I've got two 7Ds, a 10-20, a 24-105, 70-200 2.8, 180 3.5, and a 300 2.8, and usually a 50 1.4 and 30 1.4 tossed in for good measure, as well as a flash, and maybe even my tripod if I think I need it.
I think minimalism is a mindset and method which works best for some people and uses. I've done minimalism (for differing reasons, usually mountaining or something broke...), but I prefer to have all my options available.
However, if I am going out to town, or being with friends, I usually bring as my point and shoot, if you will, my 7D with either 24-105 or 50 1.4 (or sometimes 30 1.4 now that my 50 is having issues...)
